I'm trying this:
7za.exe a "C:\Disc.7z" "C:\test" -v20000000b -m0=BCJ -bd
But if I already have created the file
C:\Disc.7z then 7zip don't compress nothing and sends me this output:
System error: File already exist.
I've tried with the switch "-y", but 7zip is not doing any question...
So... Can't overwrite the file? I've tried the switch "-aoa" but does nothing too...
