Instance Property


A file system-specific representation of the receiver.


@property(readonly) const char *fileSystemRepresentation;


The returned C string will be automatically freed just as a returned object would be released; your code should copy the representation or use getFileSystemRepresentation:maxLength: if it needs to store the representation outside of the memory context in which the representation was created.

Raises an NSCharacterConversionException if the receiver can’t be represented in the file system’s encoding. It also raises an exception if the receiver contains no characters.

Note that this method only works with file paths (not, for example, string representations of URLs).

To convert a char * path (such as you might get from a C library routine) to an NSString object, use the stringWithFileSystemRepresentation:length: method on NSFileManager.

Working with Paths

+ pathWithComponents:

Returns a string built from the strings in a given array by concatenating them with a path separator between each pair.


The file-system path components of the receiver.

- completePathIntoString:caseSensitive:matchesIntoArray:filterTypes:

Interprets the receiver as a path in the file system and attempts to perform filename completion, returning a numeric value that indicates whether a match was possible, and by reference the longest path that matches the receiver.

- getFileSystemRepresentation:maxLength:

Interprets the receiver as a system-independent path and fills a buffer with a C-string in a format and encoding suitable for use with file-system calls.


A Boolean value that indicates whether the receiver represents an absolute path.


The last path component of the receiver.


The path extension, if any, of the string as interpreted as a path.


A new string that replaces the current home directory portion of the current path with a tilde (~) character.

- stringByAppendingPathComponent:

Returns a new string made by appending to the receiver a given string.

- stringByAppendingPathExtension:

Returns a new string made by appending to the receiver an extension separator followed by a given extension.


A new string made by deleting the last path component from the receiver, along with any final path separator.


A new string made by deleting the extension (if any, and only the last) from the receiver.


A new string made by expanding the initial component of the receiver to its full path value.


A new string made from the receiver by resolving all symbolic links and standardizing path.


A new string made by removing extraneous path components from the receiver.

- stringsByAppendingPaths:

Returns an array of strings made by separately appending to the receiver each string in a given array.
