Answer : The ZIP format doesn't allow for encrypting file lists. This means that file lists are viewable by anyone. Only the contents of the files is encrypted, which means that no one can read the file without your password. Due to this, 7-Zip only asks for your password before unzipping. If you need a format that encrypts the file list, use 7Z and make sure you check "Encrypt File Names". For the more technical minded, the ZIP specification doesn't allow for encryption of the Central Directory. You will be prompted for a password when you try to extract the files. To simply view the contents of the archive does not require a password. If you would like to obfuscate the contents of the archive, compress the directory into an archive, and then compress that archive with a password. Thus, you will have to extract the archive with a password, to pull out the archived (and obfuscated) contents. A generalized solution that works for all zip programs (WI...

Answer : By nature if you want the file to be encrypted, it needs to be unpacked and repacked, since the whole archive needs to be encrypted with the password. Would it work for you to zip the zip file? Use no/low compression and encrypt the original zip file. Its a lot quicker than repacking the original files.

Answer : Try zip -F science_team_meeting_archive.zip -O science_team_meeting_archive.fixed.zip If that doesn't work, you just need more 'F's zip -FF science_team_meeting_archive.zip -O science_team_meeting_archive.fixed.zip If either of these work, you then unzip normally with: unzip science_team_meeting_archive.fixed.zip For more info about this, use: man zip 7z x I had the same issue with unzip %x on Linux for a .zip file larger than 4GB, compounded with a only DEFLATED entries can have EXT descriptor error. The command 7z x resolved all my issues though. Be careful though, the command 7z x will extract all files with a path rooted in the current directory. The option -o allows to specify an output directory.
