FileRealCase

Get real upper/lower case of a file or folder name

You are now following this Submission

Get correct case of file or folder by repeated calls of DIR

FileName = FileRealCase(FileName)
INPUT:
FileName: String, absolute path of an existing file or folder.
UNC paths are accepted.
OUTPUT:
FileName: String, absolute path with upper/lower case as set in the file system.

Matlab remembers the path as accessed in under Windows:
pathname = upper(fileparts(which('plot.m')));
% >> C:\PROGRAMME\MATLAB651\TOOLBOX\MATLAB\GRAPH2D
cd(pathname)
which('plot.m')
% >> C:\PROGRAMME\MATLAB651\TOOLBOX\MATLAB\GRAPH2D\plot.m
FileRealCase(which('plot.m'))
% >> C:\Programme\Matlab651\toolbox\matlab\graph2d\plot.m

I assume, this function is useful under Windows only, but it considers the Unix naming scheme also.

Matlab's WHICH can find the correct case of files inside the Matlab path also. But this fails for files in the current folder, if the folder was selected using a string with wrong case.
