Hi monks (specially tye && tilly),

Sorry I took long to give you feed back, but I try a lot your suggetions, getting sometimes very close without never found the way to get trought that problem. I finally get a ISO certified head hack x:- {

But after a good sleep (+ 1 hour for time changing), I did few last test and tought that this is really a Windows problem who have problem dealing with filenames with non-standard characters. I was about to write you all I've done since when ... Surprise! It works find?!?!?!

I have been induced in error by corrupted files and not because they were containing special characters. And the trace I wrote make me tought I was right,... but I wasn't.

I'm putting the code I wrote for those who are sceptical like I was and certify that I used it to copy files with French accents on Win2k sp4 and XP sp2, from FAT32 and/or NTFS to Fat32 and/or NTFS.
