Christopher Newport University's network file storage allows for files that are damaged or deleted to be restored from snapshots.  Mac users must file a help desk ticket to request that their file be restored, but Windows users can restore files on their own.  File snapshots are taken three times a day, so your latest edits may not be in the snapshot.

To restore a file on Windows, navigate to the folder containing the file and right-click on it.  From the menu that comes up, choose Properties.

Select the Previous Versions tab, click on the date of the snapshot and click open.

The snapshot will open.  You can then move the files into your active drive by dragging them there.
