If you are looking for software to help you undelete files on Mac, you’ve come to the right place. Disk Drill is the premier file recovery app for Mac OS X. If you’ve emptied your Trash and then realized that you need one of the files you deleted, we can help. Read on to learn all about how to undelete files on Mac — whether they are on your hard drive, an external drive, flash drive or camera disk.

Below is just a quick overview of the steps. For detailed tutorials, see How to Install Disk Drill and How to Recover Lost Files with Disk Drill Basic in our Knowledgebase. Note that there are special steps you should take if you are trying to recover files from your Mac's internal hard drive.

Undelete files on a Mac using Disk Drill Data Recovery software

Use these steps to undelete files from your OS X computer or laptop.

1. Download and Install Disk Drill for Mac

Download and install Disk Drill for Mac. Don’t download the file to the device that has lost data as this risks overwriting the items you hope to recover. If the deleted information was on your computer’s main disk, use an external device to download and install the software.

2. Connect Device to Your Mac

Connect an external device if necessary and launch the application. Select the device from the list of available disks in the main window.

3. Start Scanning for Lost Files

Click the Recover button to start scanning the selected device for deleted data. For the best recovery results, you should allow Disk Drill to run all of its scanning algorithms in the optimal order. You can select this option or choose to run a Quick scan to search for recently deleted data or a Deep scan that searches the device on a sector level to reconstruct hard to find files. We suggest that using the full scanning power of Disk Drill will allow you to recover the maximum amount of data. Scans can be paused and restarted at your convenience and the results can be filtered so you only see the recovered files that matter to you.

Frequently Asked Questions

Updated on by Disk Drill Team

Can I recover deleted files on Mac?

Yes, you can. Deleted files can be restored with data recovery software on your Mac. When macOS deletes a file, it does not physically remove it from its storage media. It simply marks the space previously occupied by the files as available for use. Until that space is reused and the data is overwritten, the original file can be recovered.

How to recover permanently deleted files on Mac?

To recover permanently deleted files from a Mac:

  1. Download, install and launch Disk Drill.
  2. Select the disk that contained the deleted files.
  3. Click the Recover button to initiate the scanning algorithms.
  4. Preview the list of recoverable files.
  5. Select the files to be recovered and a new storage location for them.
  6. Click Recover to restore the data.

How do I recover deleted files on my Mac for free?

Recovery Vault is a feature included in the free version of Disk Drill that can recover deleted files from your Mac.
