The first thing you should know is that deleting a file means the entry for this file has been erased, not the content of this file. Not however, that the space that was once taken by the item is now labeled as "vacant" by the system. So if you save new data to the drive, the recovery process will be somewhat trickier.
So tip 1: if you have deleted a file accidentally and would like to recover it, don't write anything new to the disk where the item in question was located. Ideally don't access this disk at all.
For Mac users, you might know there is an option named as "Erase a drive" option of Apple's disk utility. If the default setting has not been changed while you are using this function, "Quick Erase" will be performed. That operation rewrites the new empty disk directory over an old one. As a result the contents of the old directory stay intact and can be recovered unless it was written over. Another option offered by Apple's disk utility is "Secure Erase". This option you have to be very careful because not only all data will be lost and also you are very likely unable to take them back once you use this option. Or it can be said almost no third-party tool can be able to recover the data once using "Secure Erase".
