I encrypted a ton of files with 7zip AES 256 bit, but now I want to change the passwords. I'm hoping I could just enter my current password, then tell it what new password I want and it do it, but I don't see an option to do that. I also sent a bunch of these files up to the cloud so if I have to downoad them all, decrypt them all, then re-encrypt them all, and reload them back up the cloud, which will take forever.

What's the best way to change the password?

7-Zip must rewrite full archive, if you change password.
