How to recover deleted files mac without software

How to recover deleted files mac without software? We may ask the same question on forums when we accidentally delete important files on our Mac. 
 
Fortunately, there are few possible ways to recover deleted files on MAC OS X. We can recover deleted files on Mac without software by operating "Undo Move", restoring deleted files from Trash, or recovering deleted files from Time Machine.

Method 1. Recover deleted files by operating "Undo Move".

If the last thing we did in the Folder was to delete files, we can select Edit > Undo Move (Command-Z) to return deleted files to their previous positions.

Method 2. Restore deleted files from Trash.

Files that we've deleted normally were sent to the Trash. The Trash will hold our deleted files until we empty the Trash. So Trash is the first place to look when we delete files. If the deleted files can be found in Trash, we can drag those files out or put back them.

Method 3. Recover deleted files from Time Machine.

Time Machine is useful for us to back up our files. If we have backed up those deleted files with Time Machine, we can restore our deleted file from there.
 
However, those ways can't work if we have emptied Trash and we have no backup for the deleted files. Under this situation, we should find a best Mac data recovery software to recover deleted files.
