I have made a .ppt file, I protected it with a password, but I can't unlock it. I want to remove the password but it is highly protected. How can I open that file?
You can try using Office Password Unlocker. It is a software that uses brute force to unlock your file. This means that it automatically searches for all combinations of letters and numbers until it cracks the password. A good aspect about this is that it works with all office files and not only with PPT.
