how can i put a password on a powerpoint file so it can't be opened without the password?

Answer 1

Well, it depends! If your using Office, stick it in a folder and right click and secure it w/a password.

If your using XP, there a couple ways you can do this. Stick it into a folder and right click and encrypt it into a zip file and secure it w/a password. You can also try this free program called Folder Locker

Answer 2

If you are using Microsoft PowerPoint:
Under the Tools menu, click Options.
Click the Security tab.
You can add the 'password to open' or the 'password to modify' from there. The difference is, 'password to open' will be asked every time you open the document. While 'password to modify' will only be needed if you want to make and save a change.
Click OK, then reenter the password.
Save the document.

This also works in all Microsoft Office Applications
