Yes yes ... you can recover your files that are deleted by you or some one else from recycle bin . Only one thing is that , you can recove the deleted files that are lastly deleted .
That means if your A file is deleted , you can recover the same untill your another any B file is not deleted . Once the B file is deleted you can recover B file but you can not recover A file .
Here is the link . . .
Happy undeleting !!
