How to Recover Deleted Files from Your Computer
-Windows
-Mac OS X
-Linux
If you’ve deleted a critical file, it may seem at first that it’s gone forever. If you act quickly, though, you may be able to recover that file and return it to its rightful place on your hard drive. Follow this guide to recover your lost files in Windows, OS X, or Linux
Method 2 of 3: Mac OS X
1.Check your Mac’s Trash. The Trash section of your Mac holds files before they are permanently deleted. If you find the file in your Trash, you can restore it to its original location or drag it to somewhere else on your computer.
2.Immediately stop accessing the drive. If your files are not found in the Trash, don’t save or delete anything from your computer. Your chances of recovering the file are much higher if you don’t save anything new. This is because when a file is deleted, it is actually just set to be overwritten. If no new data has overwritten the original file, then it can usually be recovered.
3.Download a data recovery program. Do not download or install the program to the same disk that youa re trying to recover files from. There are a variety of programs available for Mac OS X that will allow you to search for deleted files. Some of the more popular programs include:
• Data Rescue
4.Boot from your recovery software image. Some data recovery programs come with a bootable image that bypasses the OS X operating system. Booting from this image may allow your data recovery software to find more files.
• Insert the bootable disc into your Mac.
Hold the C key until the Apple logo appears. Your computer will load directly into the data recovery program.
5.Connect a recovery drive. In order for Mac recovery software to work, you will need to attach a USB drive, or designate a separate internal drive. If you are connecting an external drive, make sure that it is a USB 2.0 or Firewire device, as USB 1.0 will result in much slower processing.

6.Specify your scan settings. You will be asked to choose where you want to scan for files, so be sure to choose the hard drive that the files were originally located on. You will alos typically be given an option between a Quick scan or a Deep/Full scan.
• A Quick scan will find most of the files that can be recovered, and the process is usually fairly quick. It is recommended that you try a Quick scan first.
A Deep scan will find more files than a Quick scan, but takes significantly longer to perform. For large hard drives and slow computers, a Deep scan could take over a day to complete.
7.Select the files you want to recover. Once the scan is finished running, you will be presented with a list of files that can be recovered. Use the Preview option to ensure that the file is completely intact before marking it for Recovery.
• File names will often be changed from their original because their filer structure was destroyed during the delete process.
• Many files will not be recoverable, because parts of the file have been overwritten.
8.Recover your files. If you are attempting to recover a large number of files, try recovering only the most essential files first. This will help ensure that your most important files stay uncorrupted. The recovered files will be copied to the recovery drive that you plugged in before starting.
