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)
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.
FullName: Char or cell string, file or folder name with absolute path.
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\'
% ==> '\\Server\Folder\File.ext'
WHICH: only for existing files, ~24 times slower.
System.IO.FileInfo: .NET (thanks Urs), more features, ~50 times slower. "/.." 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
Installation: See ReadMe.txt
