If you want to enhance the security and do not want others to view the contents of your compressed folder, you can assign password to the compressed folder or zip file.

1. Locate your compressed folder or zip file, then open the folder by double clicking on it.

2. From the File menu, choose “Add a password…” (Encrypt in Windows Me), and key in your password twice then click on OK.

Note that all of the files in compressed folder are password-protected at the time of encryption or password adding. Any subsequent files will not be password-protected, to password protect subsequent files, the password needs to be removed and added again.
