fileparts - Parts of file name and path

Syntax

[pathstr, name, ext, versn] = fileparts(filename)

Description

[pathstr, name, ext, versn] = fileparts(filename) returns the path name, file name, extension, and version for the specified file. filename is a string enclosed in single quotes. The returned ext field contains a dot (.) before the file extension.

The fileparts function is platform dependent.

You can reconstruct the file from the parts using

fullfile(pathstr,[name ext versn])

Examples

Return the pieces of a file specification string to the separate string outputs pathstr, name, ext, and versn. The full file specification is

file = '\home\user4\matlab\classpath.txt';

The character used to separate the segments of a path name is dependent on the operating system you are currently running on. In this example, it is the backslash (\) character, which is used as a separator on Microsoft Windows platforms. Use the filesep function to insert the correct separator character:

sep = filesep;
file = ['' sep 'home' sep 'user4' sep 'matlab' sep ...
        'classpath.txt' ''];

Use fileparts to return the path name, file name, user name, and file version, if there is one:

[pathstr, name, ext, versn] = fileparts(file)

pathstr =
   \home\user4\matlab

name =
   classpath

ext =
   .txt

versn =
     ''

Remarks

On Windows platforms, C:\ and C: are two distinct entities, where C:\ (with backslash) is the C drive in your computer, and C: (without backslash) represents the current working directory.
