Member Enumeration Documentation

◆ FollowSymlinks

enum juce::File::FollowSymlinks

strong

Enumerator

no

Requests that a file system traversal should not follow any symbolic links.

noCycles

Requests that a file system traversal may follow symbolic links, but should attempt to skip any symbolic links to directories that may cause a cycle.

yes

Requests that a file system traversal follow all symbolic links.

Use with care, as this may produce inconsistent results, or fail to terminate, if the filesystem contains cycles due to symbolic links.

◆ SpecialLocationType

enum juce::File::SpecialLocationType

A set of types of location that can be passed to the getSpecialLocation() method.

Enumerator
userHomeDirectory	The user's home folder. This is the same as using File ("~").
userDocumentsDirectory	The user's default documents folder. On Windows, this might be the user's "My Documents" folder. On the Mac it'll be their "Documents" folder. Linux doesn't tend to have one of these, so it might just return their home folder.
userDesktopDirectory	The folder that contains the user's desktop objects.
userMusicDirectory	The most likely place where a user might store their music files.
userMoviesDirectory	The most likely place where a user might store their movie files.
userPicturesDirectory	The most likely place where a user might store their picture files.
userApplicationDataDirectory	The folder in which applications store their persistent user-specific settings. On Windows, this might be "\Documents and Settings\username\Application Data". On the Mac, it might be "~/Library". If you're going to store your settings in here, always create your own sub-folder to put them in, to avoid making a mess. On GNU/Linux it is "~/.config".
commonApplicationDataDirectory	An equivalent of the userApplicationDataDirectory folder that is shared by all users of the computer, rather than just the current user. On the Mac it'll be "/Library", on Windows, it could be something like "\Documents and Settings\All Users\Application Data". On GNU/Linux it is "/opt". Depending on the setup, this folder may be read-only.
commonDocumentsDirectory	A place to put documents which are shared by all users of the machine. On Windows this may be somewhere like "C:\Users\Public\Documents", on OSX it will be something like "/Users/Shared". Other OSes may have no such concept though, so be careful.
tempDirectory	The folder that should be used for temporary files. Always delete them when you're finished, to keep the user's computer tidy!
currentExecutableFile	Returns this application's executable file. If running as a plug-in or DLL, this will (where possible) be the DLL rather than the host app. On the mac this will return the unix binary, not the package folder - see currentApplicationFile for that. See also invokedExecutableFile, which is similar, but if the exe was launched from a file link, invokedExecutableFile will return the name of the link.
currentApplicationFile	Returns this application's location. If running as a plug-in or DLL, this will (where possible) be the DLL rather than the host app. On the mac this will return the package folder (if it's in one), not the unix binary that's inside it - compare with currentExecutableFile.
invokedExecutableFile	Returns the file that was invoked to launch this executable. This may differ from currentExecutableFile if the app was started from e.g. a link - this will return the name of the link that was used, whereas currentExecutableFile will return the actual location of the target executable.
hostApplicationPath	In a plugin, this will return the path of the host executable.
windowsSystemDirectory	On a Windows machine, returns the location of the Windows/System32 folder.
globalApplicationsDirectory	The directory in which applications normally get installed. So on windows, this would be something like "C:\Program Files", on the Mac "/Applications", or "/usr" on linux.
globalApplicationsDirectoryX86	On a Windows machine, returns the directory in which 32 bit applications normally get installed. On a 64 bit machine this would be something like "C:\Program Files (x86)", whereas for 32 bit machines this would match globalApplicationsDirectory and be something like "C:\Program Files". See also globalApplicationsDirectory
windowsLocalAppData	On a Windows machine returns the LOCALAPPDATA% folder.

◆ TypesOfFileToFind

enum juce::File::TypesOfFileToFind

Used in file searching, to specify whether to return files, directories, or both.

Enumerator
findDirectories	Use this flag to indicate that you want to find directories.
findFiles	Use this flag to indicate that you want to find files.
findFilesAndDirectories	Use this flag to indicate that you want to find both files and directories.
ignoreHiddenFiles	Add this flag to avoid returning any hidden files in the results.

Constructor & Destructor Documentation

◆ File() [1/4]

juce::File::File ( )

default

Creates an (invalid) file object.

The file is initially set to an empty path, so getFullPathName() will return an empty string.

You can use its operator= method to point it at a proper file.

Referenced by getCurrentWorkingDirectory().

◆ File() [2/4]

juce::File::File ( const String & absolutePath )

Creates a file from an absolute path.

If the path supplied is a relative path, it is taken to be relative to the current working directory (see File::getCurrentWorkingDirectory()), but this isn't a recommended way of creating a file, because you never know what the CWD is going to be.

On the Mac/Linux, the path can include "~" notation for referring to user home directories.

◆ File() [3/4]

juce::File::File ( const File & )

Creates a copy of another file object.

◆ ~File()

juce::File::~File ( )

default

Destructor.

◆ File() [4/4]

juce::File::File ( File && )

noexcept

Move constructor.

Member Function Documentation

◆ addToDock()

void juce::File::addToDock ( ) const

OSX ONLY - Adds this file to the OSX dock.

◆ addTrailingSeparator()

static String juce::File::addTrailingSeparator ( const String & path )

static

Adds a separator character to the end of a path if it doesn't already have one.

◆ appendData()

bool juce::File::appendData	(	const void *	dataToAppend,
		size_t	numberOfBytes
	)		const

Appends a block of binary data to the end of the file.

This will try to write the given buffer to the end of the file.

Returns: false if it can't write to the file for some reason

◆ appendText()

bool juce::File::appendText	(	const String &	textToAppend,
		bool	asUnicode = `false`,
		bool	writeUnicodeHeaderBytes = `false`,
		const char *	lineEndings = `"\r\n"`
	)		const

Appends a string to the end of the file.

This will try to append a text string to the file, as either 16-bit unicode or 8-bit characters in the default system encoding.

It can also write the 'ff fe' unicode header bytes before the text to indicate the endianness of the file.

If lineEndings is nullptr, then line endings in the text won't be modified. If you pass "\\n" or "\\r\\n" then this function will replace any existing line feeds.

See also: replaceWithText

◆ areFileNamesCaseSensitive()

static bool juce::File::areFileNamesCaseSensitive ( )

static

Indicates whether filenames are case-sensitive on the current operating system.

◆ containsSubDirectories()

bool juce::File::containsSubDirectories ( ) const

Returns true if this file is a directory that contains one or more subdirectories.

See also: isDirectory, findChildFiles

◆ copyDirectoryTo()

bool juce::File::copyDirectoryTo ( const File & newDirectory ) const

Copies a directory.

Tries to copy an entire directory, recursively.

If this file isn't a directory or if any target files can't be created, this will return false.

Parameters

newDirectory the directory that this one should be copied to. Note that this is the name of the actual directory to create, not the directory into which the new one should be placed, so there must be enough write privileges to create it if it doesn't exist. Any files inside it will be overwritten by similarly named ones that are copied.

◆ copyFileTo()

bool juce::File::copyFileTo ( const File & targetLocation ) const

Copies a file.

Tries to copy a file to a different location. If the target file already exists, this will attempt to delete it first, and will fail if this can't be done.

Returns: true if the operation succeeds

◆ copyInternal()

bool juce::File::copyInternal ( const File & ) const

private

Referenced by moveInternal().

◆ create()

Result juce::File::create ( ) const

Creates an empty file if it doesn't already exist.

If the file that this object refers to doesn't exist, this will create a file of zero size.

If it already exists or is a directory, this method will do nothing.

If the parent directories of the File do not exist then this method will recursively create the parent directories.

Returns: a result to indicate whether the file was created successfully, or an error message if it failed.

See also: createDirectory

◆ createDirectory()

Result juce::File::createDirectory ( ) const

Creates a new directory for this filename.

This will try to create the file as a directory, and will also create any parent directories it needs in order to complete the operation.

Returns: a result to indicate whether the directory was created successfully, or an error message if it failed.

See also: create

◆ createDirectoryInternal()

Result juce::File::createDirectoryInternal ( const String & fileName ) const

private

References juce::anonymous_namespace{juce_posix_SharedCode.h}::getResultForReturnValue(), and juce::String::toUTF8().

◆ createFileWithoutCheckingPath()

static File juce::File::createFileWithoutCheckingPath ( const String & absolutePath )

staticnoexcept

Creates a file that simply contains this string, without doing the sanity-checking that the normal constructors do.

Best to avoid this unless you really know what you're doing.

◆ createInputStream()

std::unique_ptr<FileInputStream> juce::File::createInputStream ( ) const

Creates a stream to read from this file.

Note that this is an old method, and actually it's usually best to avoid it and instead use an RAII pattern with an FileInputStream directly, e.g.

FileInputStream input (fileToOpen);
 
if (input.openedOk())
{
    input.read (etc...
}

Returns: a stream that will read from this file (initially positioned at the start of the file), or nullptr if the file can't be opened for some reason

See also: createOutputStream, loadFileAsData

◆ createLegalFileName()

static String juce::File::createLegalFileName ( const String & fileNameToFix )

static

Returns a version of a filename with any illegal characters removed.

This will return a copy of the given string after removing characters that are not allowed in a legal filename, and possibly shortening the string if it's too long.

Because this will remove slashes, don't use it on an absolute pathname - use createLegalPathName() for that.

See also: createLegalPathName

◆ createLegalPathName()

static String juce::File::createLegalPathName ( const String & pathNameToFix )

static

Returns a version of a path with any illegal characters removed.

Similar to createLegalFileName(), but this won't remove slashes, so can be used on a complete pathname.

See also: createLegalFileName

◆ createOutputStream()

std::unique_ptr<FileOutputStream> juce::File::createOutputStream ( size_t bufferSize = 0x8000 ) const

Creates a stream to write to this file.

Note that this is an old method, and actually it's usually best to avoid it and instead use an RAII pattern with an FileOutputStream directly, e.g.

FileOutputStream output (fileToOpen);
 
if (output.openedOk())
{
    output.read etc...
}

If the file exists, the stream that is returned will be positioned ready for writing at the end of the file. If you want to write to the start of the file, replacing the existing content, then you can do the following:

FileOutputStream output (fileToOverwrite);
 
if (output.openedOk())
{
    output.setPosition (0);
    output.truncate();
    ...
}

Returns: a stream that will write to this file (initially positioned at the end of the file), or nullptr if the file can't be opened for some reason

See also: createInputStream, appendData, appendText

◆ createShortcut()

bool juce::File::createShortcut	(	const String &	description,
		const File &	linkFileToCreate
	)		const

Windows ONLY - Creates a win32 .LNK shortcut file that links to this file.

◆ createSymbolicLink() [1/2]

bool juce::File::createSymbolicLink	(	const File &	linkFileToCreate,
		bool	overwriteExisting
	)		const

Tries to create a symbolic link and returns a boolean to indicate success.

◆ createSymbolicLink() [2/2]

static bool juce::File::createSymbolicLink	(	const File &	linkFileToCreate,
		const String &	nativePathOfTarget,
		bool	overwriteExisting
	)

static

Create a symbolic link to a native path and return a boolean to indicate success.

Use this method if you want to create a link to a relative path or a special native file path (such as a device file on Windows).

◆ createTempFile()

static File juce::File::createTempFile ( StringRef fileNameEnding )

static

Returns a temporary file in the system's temp directory.

This will try to return the name of a non-existent temp file. To get the temp folder, you can use getSpecialLocation (File::tempDirectory).

◆ deleteFile()

bool juce::File::deleteFile ( ) const

Deletes a file.

If this file is actually a directory, it may not be deleted correctly if it contains files. See deleteRecursively() as a better way of deleting directories.

If this file is a symlink, then the symlink will be deleted and not the target of the symlink.

Returns: true if the file has been successfully deleted (or if it didn't exist to begin with).

See also: deleteRecursively

References exists(), fullPath, isDirectory(), isSymbolicLink(), and juce::String::toUTF8().

Referenced by moveInternal().

◆ deleteRecursively()

bool juce::File::deleteRecursively ( bool followSymlinks = false ) const

Deletes a file or directory and all its subdirectories.

If this file is a directory, this will try to delete it and all its subfolders. If it's just a file, it will just try to delete the file.

Parameters

followSymlinks If true, then any symlink pointing to a directory will also recursively delete the contents of that directory

Returns: true if the file and all its subfolders have been successfully deleted (or if it didn't exist to begin with).

See also: deleteFile

◆ descriptionOfSizeInBytes()

static String juce::File::descriptionOfSizeInBytes ( int64 bytes )

static

Utility function to convert a file size in bytes to a neat string description.

So for example 100 would return "100 bytes", 2000 would return "2 KB", 2000000 would produce "2 MB", etc.

◆ exists()

bool juce::File::exists ( ) const

Checks whether the file actually exists.

Returns: true if the file exists, either as a file or a directory.

See also: existsAsFile, isDirectory

References juce::gl::access, fullPath, juce::String::isNotEmpty(), and juce::String::toUTF8().

Referenced by deleteFile(), existsAsFile(), hasWriteAccess(), and juce::FileOutputStream::openHandle().

◆ existsAsFile()

bool juce::File::existsAsFile ( ) const

Checks whether the file exists and is a file rather than a directory.

Returns: true only if this is a real file, false if it's a directory or doesn't exist

See also: exists, isDirectory

References exists(), and isDirectory().

◆ findChildFiles() [1/2]

int juce::File::findChildFiles	(	Array< File > &	results,
		int	whatToLookFor,
		bool	searchRecursively,
		const String &	wildCardPattern = `"*"`,
		FollowSymlinks	followSymlinks = `FollowSymlinks::yes`
	)		const

Searches inside a directory for files matching a wildcard pattern.

Note that there's a newer, better version of this method which returns the results array, and in almost all cases, you should use that one instead! This one is kept around mainly for legacy code to use.

◆ findChildFiles() [2/2]

Array<File> juce::File::findChildFiles	(	int	whatToLookFor,
		bool	searchRecursively,
		const String &	wildCardPattern = `"*"`,
		FollowSymlinks	followSymlinks = `FollowSymlinks::yes`
	)		const

Searches this directory for files matching a wildcard pattern.

Assuming that this file is a directory, this method will search it for either files or subdirectories whose names match a filename pattern. Note that the order in which files are returned is completely undefined!

Parameters

whatToLookFor	a value from the TypesOfFileToFind enum, specifying whether to return files, directories, or both. If the ignoreHiddenFiles flag is also added to this value, hidden files won't be returned
searchRecursively	if true, all subdirectories will be recursed into to do an exhaustive search
wildCardPattern	the filename pattern to search for, e.g. "*.txt"
followSymlinks	the method that should be used to handle symbolic links

◆ findFileSystemRoots()

static void juce::File::findFileSystemRoots ( Array< File > & results )

static

Creates a set of files to represent each file root.

e.g. on Windows this will create files for "c:\", "d:\" etc according to which ones are available. On the Mac/Linux, this will probably just add a single entry for "/".

◆ getChildFile()

File juce::File::getChildFile ( StringRef relativeOrAbsolutePath ) const

Returns a file that represents a relative (or absolute) sub-path of the current one.

This will find a child file or directory of the current object.

e.g. File ("/moose/fish").getChildFile ("foo.txt") will produce "/moose/fish/foo.txt". File ("/moose/fish").getChildFile ("haddock/foo.txt") will produce "/moose/fish/haddock/foo.txt". File ("/moose/fish").getChildFile ("../foo.txt") will produce "/moose/foo.txt".

If the string is actually an absolute path, it will be treated as such, e.g. File ("/moose/fish").getChildFile ("/foo.txt") will produce "/foo.txt"

◆ getFileName()

String juce::File::getFileName ( ) const

Returns the last section of the pathname.

Returns just the final part of the path - e.g. if the whole path is "/moose/fish/foo.txt" this will return "foo.txt".

For a directory, it returns the final part of the path - e.g. for the directory "/moose/fish" it'll return "fish".

If the filename begins with a dot, it'll return the whole filename, e.g. for "/moose/.fish", it'll return ".fish"

See also: getFullPathName, getFileNameWithoutExtension

◆ getNonexistentChildFile()

File juce::File::getNonexistentChildFile	(	const String &	prefix,
		const String &	suffix,
		bool	putNumbersInBrackets = `true`
	)		const

Chooses a filename relative to this one that doesn't already exist.

If this file is a directory, this will return a child file of this directory that doesn't exist, by adding numbers to a prefix and suffix until it finds one that isn't already there.

If the prefix + the suffix doesn't exist, it won't bother adding a number.

e.g. File ("/moose/fish").getNonexistentChildFile ("foo", ".txt", true) might return "/moose/fish/foo(2).txt" if there's already a file called "foo.txt".

Parameters

prefix	the string to use for the filename before the number
suffix	the string to add to the filename after the number
putNumbersInBrackets	if true, this will create filenames in the format "prefix(number)suffix", if false, it will leave the brackets out.

◆ getNonexistentSibling()

File juce::File::getNonexistentSibling ( bool putNumbersInBrackets = true ) const

Chooses a filename for a sibling file to this one that doesn't already exist.

If this file doesn't exist, this will just return itself, otherwise it will return an appropriate sibling that doesn't exist, e.g. if a file "/moose/fish/foo.txt" exists, this might return "/moose/fish/foo(2).txt".

Parameters

putNumbersInBrackets whether to add brackets around the numbers that get appended to the new filename.

◆ getNumberOfChildFiles()

int juce::File::getNumberOfChildFiles	(	int	whatToLookFor,
		const String &	wildCardPattern = `"*"`
	)		const

Searches inside a directory and counts how many files match a wildcard pattern.

Assuming that this file is a directory, this method will search it for either files or subdirectories whose names match a filename pattern, and will return the number of matches found.

This isn't a recursive call, and will only search this directory, not its children.

Parameters

whatToLookFor	a value from the TypesOfFileToFind enum, specifying whether to count files, directories, or both. If the ignoreHiddenFiles flag is also added to this value, hidden files won't be counted
wildCardPattern	the filename pattern to search for, e.g. "*.txt"

Returns: the number of matches found

See also: findChildFiles, RangedDirectoryIterator

◆ getParentDirectory()

File juce::File::getParentDirectory ( ) const

◆ moveFileTo()

bool juce::File::moveFileTo ( const File & targetLocation ) const

Moves or renames a file.

Tries to move a file to a different location. If the target file already exists, this will attempt to delete it first, and will fail if this can't be done.

Note that the destination file isn't the directory to put it in, it's the actual filename that you want the new file to have.

Also note that on some OSes (e.g. Windows), moving files between different volumes may not be possible.

Copies from another file object.

◆ operator=() [2/3]

File& juce::File::operator= ( const String & newAbsolutePath )

Sets the file based on an absolute pathname.

If the path supplied is a relative path, it is taken to be relative to the current working directory (see File::getCurrentWorkingDirectory()), but this isn't a recommended way of creating a file, because you never know what the CWD is going to be.

On the Mac/Linux, the path can include "~" notation for referring to user home directories.

References moveInternal().

◆ replaceWithData()

bool juce::File::replaceWithData	(	const void *	dataToWrite,
		size_t	numberOfBytes
	)		const

Replaces this file's contents with a given block of data.

This will delete the file and replace it with the given data.

A nice feature of this method is that it's safe - instead of deleting the file first and then re-writing it, it creates a new temporary file, writes the data to that, and then moves the new file to replace the existing file. This means that if the power gets pulled out or something crashes, you're a lot less likely to end up with a corrupted or unfinished file..

Returns true if the operation succeeds, or false if it fails.
