FAQ
- Can this remove a password I do not know?No. Removing an open password requires opening the file, which requires the password. This is for decks you are entitled to open, not for recovering lost passwords.
- What can be removed without a password?Write protection and the marked-as-final flag, because they are settings inside a file that is already readable — unlike an open password, which encrypts it.
- Which formats can protection be removed from?PPT, PPTX and ODP — the same formats that can carry it. Removing it is simply saving the presentation again with the protection settings cleared.
- How do I confirm the protection is really gone?Save the file and open it again without supplying a password. If it opens, the open password is gone; checking the protection properties on the in-memory object is not the same test.
