Normalize file path with WinAPI [duplicate]

Answer 1

There are odd cases. For example, "c:\windows..\data\myfile.txt" is the same as "c:\data.\myfile.txt" and "c:\data\myfile.txt". You can have any number of "\.\" and "\..\" in there. You might look into the Windows API function GetFullPathName. It might do canonicalization for you.
