I never think about that the files deleted from the Windows Recycling Bin Could be recovered as before. Actually, my cousin tell me it is easy to do it. It said that, the files you deleted is still in the drive until new files were put in to replace them. You just delete the saving path of the file and the physical files were still kept in. Just some data recovery could solve th problem. So funny!!!
Well that's true. There is nothing actually like "deletion" in pc it's just "replacement". Old/non-usable files got replaced by new files and we say that old files got deleted
You can also recover the files on your HD if your windows stops working by using linux. Just follow the instructions in the article on running a linux bootable flash drive posted on this thread. It will also give tips on copying your file contents to an external drive.
