I created a 7zip archive with AES encryption. I included the option to encrypt the filenames. When I updated the file however I am no longer prompted for a password to open the file and can view the filenames without a password. Newly added files are listed with a minus instead of a plus on the encrypted property and their method property shows LZMA without 7zAES as the first set of files have.
I'm using the windows 7zip file manager GUI.
Can anyone tell me if it's possible to update an archive and maitain the encryption status? Or do I have to extract and recreate the archive if I want all files to be encrypted?
