Generally, once a file is corrupt, it's gone. So what I'd do, is just recreate the changes using one of your slightly older versions of the file. This time taking care to make sure you know exactly which one you're editing. Maybe saving a copy to a USB flash drive in addition to uploading a copy somewhere.
In the amount of time you've spent looking for ways to recover the file, you probably could have recreated the changes and been done already. Always be sure to consider how much time and effort each option takes. Obviously if you could have quickly found some program to recover the file, that would have been best, but when that search came up empty, you should have switched right over to just recreating the changes. Effective time management skills are something you need to succeed in school.
Early this morning I was finishing up an assignment at home, and I sent the file to my school's server. At school where I was going to print, I found out all the changes I had made in my presentation were gone!
When I got home I opened my file and realized the changes were not saved there either. I must of screwed around with the temporary internet files.
Anyway, I was able to recover the file (I know its the most current file because it says date modified May 30 6:57 A.M.). However, when I click the file I get an error message that the file is corrupted.
So I searched online for a Powerpoint repair program but they only give demos for free, and these demos either don't work at all or come up with screwed up slides or incomplete presentations. In order to retrieve the actual files, I have to pay $35 plus, which is not worth it for retrieving one file.
So I need to know any ways to make my file "un-corrupt" so I can start working on it again. Does anyone know of free programs that can do this? Are there alternate methods that will prove successful?
I'll tell you what I've tried so far:
-I've tried the open and repair function for microsoft office, it just comes to the same error screen
-Ive tried opening with notepad but there is a jumbled mess of strange letter (I have no idea how or what program to decrypt those)
-The issue does not involve the internet, but rather the files inside my computer.
Thanks for any help. I need this problem to be fixed!!!
