GetFullPath

Full path name for partial or relative path

GetFullPath - Get absolute path of a file or folder name

This function converts a partial or relative name to an absolute full path name. The fast Mex works on Windows only, but the M-file runs on Windows, MacOS and Unix.

FullName = GetFullPath(Name, Style)

INPUT:

Name: Char, string or cell string, file or folder name with relative or absolute path.

UNC paths accepted. Path need not exist.

Style: Special styles for long file names under Windows:

'auto': Add '//?/' for long names (> 255 characters). (default)

'lean': No '//?/'.

'fat': '//?/' added for short names also.

OUTPUT:

FullName: Char or cell string, file or folder name with absolute path.

EXAMPLES:

cd(tempdir); % Assuming C:\Temp here

GetFullPath('File.Ext') % ==> 'C:\Temp\File.Ext'

GetFullPath('..\File.Ext') % ==> 'C:\File.Ext'

GetFullPath('.\File.Ext') % ==> 'C:\Temp\File.Ext'

GetFullPath('*.txt') % ==> 'C:\Temp\*.txt'

GetFullPath('D:\Folder1\..\Folder2') % ==> 'D:\Folder2'

GetFullPath('\') % ==> 'C:\', current drive!

GetFullPath('Folder\') % ==> 'C:\Temp\Folder\'

GetFullPath('\\Server\Folder\Sub\..\File.ext')

% ==> '\\Server\Folder\File.ext'

Alternatives:

WHICH: only for existing files, ~24 times slower.

System.IO.FileInfo: .NET (thanks Urs), more features, ~50 times slower.

java.io.File: "/.." and "/." are fixed by getCanonicalPath (~6 times slower),

but no completing of partial/relative path.

Tested: Matlab 2009a, 2011b, 2018b, WinXP/32, Win7/64, Win10/64
