Ok, i'm going directly to ask for the extreme:
Does anyone know how to remove the last byte on a 50M file?
As for my solution that would take a 15 sec, as it empties the file with output and rewrites it in binary.
I'm actually just working with mp3's but it's annoying amount of time (1-2) sec and the harddisk chattters alot.
AFAIK, vb, can't do it so giving me a dll made in c++ or something would be great.
