A couple years ago, my father made a backup of one of our computers using Windows Backup and Restore. It was either Windows Vista or Windows 7, not sure which. He backed up the entire computer, including Program Files, AppData, My Documents, everything, and now it is on .zip files on a WD Passport with 300GB, I'm not sure exactly what it is called. Now I am trying to decide which files to keep and which to delete. Most of what we would keep are files, as we would need CD's to use the programs, and I'm pretty sure they would install everything all over again. That pretty much leaves out Program Files, however, I'm not sure about AppData. For example, my mother used Greetings Workshop and wants some files from there, and she may want to keep some default settings she used. I am talking generally here, as I'm sure some programs have different ways of saving things in AppData.
What, if anything, should I keep from AppData, and what should I delete?

There's no universal solution to this question. No one will ever give you a comprehensive answer because there are so many applications. Each application stores its preferences differently, and you have to know for each particular application what it stores in
AppData
to decide whether it's worth saving or not.Let me give you a couple of examples:
AppData\Roaming
. I think it's worth saving, the browser will be configured the way it was, including bookmarks, and even open tabs will be restored.At the same time the data Firefox stores in
AppData\Local
are useless: there are different caches.AppData\Roaming
and (mostly) throw-away data inAppData\Local
.Yet if you used Opera Mail client, all the mails are saved in
AppData\Local
, thus you may want to keep your mail messages.AppData\Local
.AppData\Roaming
.Usually data in
AppData\Roaming
are more important than inAppData\Local
.
