I accidentally deleted important files from my drive. I already deleted
them from the trash bin as well, anything I can do to restore them?
They can be recovered but don't use the system where the files were
as they can be overwritten, making them unrecoverable (especially if you install programs or save files to it -- even browsing can overwrite as files are sometimes downloaded, saved and deleted for content in the web site).
The files are still on your drive, marked as "free space" but if you save files or do anything that could cause file writes (like web surfing), you run the risk of having the free space written over and that makes it A LOT harder to recover the files.
Go to this site: http://www.diskeeper.com/home-use/emergency-undelete/
a nd get "Emergency Undelete" (if possible, download it using another machine and place it in a flash drive or disk).
Run Emergency Undelete from the flash drive or disk on the PC that has the files and follow the directions (don't install anything yet -- simply run the "Emergency Undelete").
Follow the directions and you will recover your files.
