If you have deleted some of your files from your H drive or files from one of the shared drives then please contact The Systems Team ASAP as we should be able to recover the file(s) from our backup servers. Obviously our backups only work if the file has been saved at least once and it will only restore to the last point saved on our backup system, if you haven't saved your work and the program you are using crashes we wont be able to recover it.
