Total Commander

Master Password via Command Line and wincmd.ini

Passing a password via command line would be a big security hole, so there wouldn't be much sense to use it at all...

I would do this:
I have a f: driver crypted.
I have a passordfile named masterpsw.txt wint password in it
i have a preference in wincmd.ini
pswmasterfile=f:\masterpsw.txt
if file f:\masterpsw.txt exist (driver crypted initialized) tcmd use its content as master password else it prompt for psw.
Do it is possibile to do?

I see - no, sorry. If TC can read the masterpsw.txt, then any virus/troyan can read it too, so you could as well leave the passwords unencrypted.
