Well, at least when the path is too long (length(FileName>MAXPATH)) it can prepend \\?\ because it will fail without it anyway. I have found this issue the hard way as I checked for file existence in my program and it reported false although the file existed. So I overwrote it. IMO this is a bug. A function that claims to check for file existence should be as reliable as possible and not have some obscure side effects. > See the comments in ExpandFilenameUTF8 (I think I put a reference there). I did not find any comments that mentions long paths -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
