I was uninstalling some programs (solidworks) but i think the applet come out is something like ...."Do you want to delete everything in Drive D?", then i thought its do you want to delete and uninstall the file, and press yes.

But somewhere i sort of realise the statement sounds funny, so i go to mycomputer and monitor my D drive...and indeed the empty space is more and more...then i quickly press clt-alt-dlt and stop the process from deleting my whole D drive...

I think about 2gb of data got deleted and some are my experiment data needed for my thesis....

can anyone help?
The worst thing is that i dont know what are being deleted, cuz i dont know which files are deleted first by the computer....
I also try to check if can recover, but realised i got no recover points?!!

How, how, can anyone advise me know to recover back the deleted files???
Thanks a million!
