Any tools for recovering corrupt .PPT files?
There is one; we haven’t tried it, but it does come from Microsoft so we’ll let you judge its quality. This is an add-in that “clones” the active presentation. Supposedly, you can use this add-in to create a corruption free copy of a presentation that you suspect may be corrupted. You can find this add-in at: http://support.microsoft.com/support/kb/articles/Q193/8/48.
