not very likely. unfortunately. most temp files are just that temp. and are usually deleted from the system immediately on reboot or opening a different file in that application or just closing the file.
only thing that may exist is for Microsoft office products like word if in the control panel settings I forget the name but something about autosave/autorecovery a temp file every few min was set you might have a chance at recovery as those files usually don't get deleted for awhile.
