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 doesn't compress anything and sends me this output:
System error:
File already exist.
I've tried with the switch -y
, but 7zip does not do anything...
How can I overwrite the file?
UPDATE
I've tried the switch -aoa
but it does not work either...
