Conceptually 260 chars filename limitation can be overcome by prefixing
filenames with '\\?\': 
quoting DeleteFunction help page

In the ANSI version of this function, the name is limited to MAX_PATH
characters. To extend this limit to 32,767 wide characters, call the Unicode
version of the function and prepend "\\?\" to the path. For more information,
see Naming a File.

We already use Unicode version of Windows File functions. Only thing is left is
to add prefix :-)

Right?
