System Restore failed to recover my lost image files. Will the use of recovery software works?

therese asked: Just found out that one of our computer’s user account was lost.
I tried system restore but it only restore the lost acct without the data. It used to have image files, will it be recovered using the recovery software available?
advance thanks!

Until what extent can a data recovery software recover files?
