There are two ways to store a file. One is on the local computer and one is on some server file storage.
In any case, you'd have to have some technical information about how the files were stored before and then if they even exist now. They may have been backed up to some place or they might need to map a drive or allow you access to some share.
We can't tell. You have to contact your tech support. Only they would have the answer. There is no file recovery program that can help in this case.
1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
