There a couple apps out there that able to recover deleted files, Undelete is one, Hexamob is another, but these require root. And these specialize in stuff like pictures so not even sure they would help you out.

thank you for your reply.
This tab is not rooted and doesn't have custom recovery.
He doesn't remembre which files has deleted...a lot of files about app...but like you said, if the tablet is not rooted, is impossible to delete system files!
I know that there are a lot of apps for recover deleted files, but I am afraid to run the system restore...I don't know if this operation format the partition at low level or not...and I think that all these apps require root.
I looked for this thing and there isn't a chance to mount the tab as a drive (E:\ F:\ ...) and for this reason you can't use software normally used for recover deleted files in windows.
I am really disappointed with Android operating system.
People say that Android is an open operating system, configurable, customizable .... But I have found everything closed as are microsoft and iOS.
