  • Symbols (for example: !, $, #, %, Æ, é, ü, ½, ±, etc.)

  1. You can click Show Password to check that you have spelt the password correctly. If you do click this button, once you have checked the password be sure to uncheck Show Password.

Do not use your Massey University network login as a password for 7-Zip.
Make sure you remember your encryption password. If you lose or forget it, you will have to re-compress / re-encrypt the original file.
