I'm having problems viewing my hard drive files

[OrlandoAppDev]

So I was backupping files of our Orlando App Developers page and now I can't seem to open any of the files. All the applications are re-installed. Anyone have any inkling what could've happened and the solutions to this? I have deadline on this. Thanks!

Maybe you have accidentally deleted the backup file? 

The first place you should look after deleting a file is the Recycle Bin. It may seem a little obvious, but this back-up facility can be overlooked. If your file is in there, right-click it and select Restore from the menu. Of course, the Recycle Bin doesn’t catch every file deletion, with files that have been deleted in DOS being a particular oversight. There are utilities that will cover this inadequacy, but if you’re in DOS, then merely knowing that a deletion could be permanent should have you in the right frame of mind.

There's something may have happen to the hard drive.
