On win32 systems, stat often returns 0 for size when called for a directory. Some documentation suggests that it may sometimes return non-zero for directory size in some circumstances, but I haven't seen it myself. The '-s' file test is based on stat, so '-s' will often return 0 when used on a directory.
It might help you solve your problem if you check the return from the move function. See File::Copy for details. Maybe something like the following:
move( $source, $destination ) or die "move( $source, $destination ) fa
The error message should help you understand why the move failed. On the other hand, testing I have done on Windows XP suggests that the error messages are not very good: in my tests it returned "No such file or directory" regardless of what the actual problem was. Also, while move worked for directories within a file system, copy didn't. Neither move nor copy worked for directories when moving or copying from one drive to another but move and copy both worked when moving or copying a file from one drive to another. So it seems that File::Copy is somewhat broken, at least for Active State perl 5.10.0 on Windows XP.
