i used to save all important, most up date, refined/corrected SAS data files in sasuser directory, permanently saved in 9.1 folder of My SAS Files. But, instead of deleting temporary files from each each temporary folders, I happened to delete all temporary SAS directories/folders (tmp1, tmp2, tmp3, etc) as it would be faster. That way, I lost all the original SAS files from their permanent placees.

I tried to locate those deleted files form the windows's temp folder where SAS Temporary Files are stored. But, I could retrive only 5-7 files from there were not even not even the most up to date and refined data sets where I had over 30 different refined and final datasets in SASUSER (9.1 folder) for 12-15 projects.

Is there any easy way I can retrive those flies? Or, if i should use some data recovery software, can you suggest the free yet reliable software to do the job? (I am not going to write anything in this computer for the time being so that I hope I wold lose or overwrite in thos SAS data.)
