All my work was lost and the autorecover folder C:\Users\\AppData\Roaming\Microsoft\PowerPoint was empty. The fact that it was there after the PC crash means it must be saved somewhere. But where and what file extension? I'm using file recovery software and can recover deleted files etc. but cannot find the deleted file anywhere, it certainly is not obvious e.g. *.ppt.
