Re: FindFirstFileExW and MAX_PATH

I find it so interesting, that even a 64 bit OS, still uses that API,
limited to 260 (249 in fact) characters for directories and files.

The complete path and filename together is limited to MAX_PATH characters by
default, yes.

FindFirstFileExW tells us about the \\?\ prefix, to overcome that
limit, BUT the WIN32_FIND_DATA structure, contains just
260 characters for the cFilename section! :)

The cFilename member receives just the filename, not the complete path
leading up to the filename. When '\\?\' is used, individual components of a
path (aka each subfolder and file name) are each limited to 255 characters
max. So receiving such a filename still fits within a buffer of MAX_PATH
size regardless of whether '\\?\' is used or not.
