Password-protecting a zipped file is a good solution if your version of Windows does not support password protection. If you put the files you’d like to protect in a zip file, you can then apply a password.

1. In Windows Explorer, highlight and right-click on the files you would like to put into a zipped file.
2. Select Send to, then Zip folder (compressed). Follow the prompts to name and save the folder.
3. Double-click the zipped file, then select File and Add Password.
4. Fill out the requested information, then click Apply.
