The "Unable..." message is my die alternative to system (take a look at the first post). The "1 file copied..." and "No such file..." messages are standard DOS messages (I've just translated them from my native language, portuguese). Here's the source code who generated the two files, sorry I couldn't translate the portuguese messages, but you should understand the code (I've putted some comments tough...). Thanks a lot for your help.
