WHY CAN YOU RECOVER FILES?
When you delete something, Windows just deletes the file’s address and marks the space as free space even though the file is still there.
Until that space is overwritten with new data, that file is still easily recoverable.
HOW TO SECURELY DELETE DATA
Use a special program to delete files Eraser (http://eraser.heidi.ie/)
After deleting a file, this type of program overwrites the file a certain number times with random data. This prevents people from recovering the data.

The only surefire way to securely delete data is to physically destroy the device
