In most cases, if you accidentally delete files from your Mac, you can still end up in the macOS trash. From the trash can you can then restore the file or folder to its original locations. However, if your trash has also been cleared, then of course you have a problem.
Not only can files get lost on your Mac, you can accidentally delete that one great photo taken with your digital camera from the external SD card. The CAT Mac Data Recovery app can be your rescue app in both cases. The application makes the promise that in most cases it can recover deleted files from hard disk, SSD, USB stick, memory card, etc.
Don’t really lose files
The moment you delete a file in macOS, it will be placed in the trash, unless you delete files or folders directly using macOS Terminal or Finder.
If the trash is emptied or the files are deleted immediately, the data will still remain. The index of your hard disk (or other storage medium) only places a mark that the files have been deleted and should no longer be displayed. The files will therefore remain on the disk, but will no longer be displayed. The disk space occupied by these files is freed up and can be used again.
Of course, the deleted files will eventually be permanently erased from the disk. But this depends on the available free space on the hard disk. So it may take a while for the files to actually be overwritten and lost permanently.
Because the files are not immediately deleted, you can undo the delete mark in the file system. This will make the files available again, but please note, this is only possible if the used disk space has not yet been overwritten. For this reason, it is important to always format a Mac or hard drive before lending or selling it.
CAT Mac Data Recovery
The moment you have lost files, it is wise to take immediate action. In many cases, specialized software such as CAT Data Recovery Software can recover the deleted files.
The app supports a wide variety of file systems such as APFS, encrypted APFS, HFS +, HFS and ExFAT. The support for APFS makes the application special because the Apple Filesystem is still not supported by many similar apps.
With the free (trial) version of the app you can restore a limited number of GBs of data for free. If you want to recover more data, you have to purchase CAT Data Recovery for Mac.
Restore files from the app
CAT Mac Data Recovery uses a wizard that takes you step-by-step through a recovery process. You start with the choice: whether you want to restore individual files, all files or an entire partition.
First of all, you will look for the lost files. Select the files or folders you want to restore. You can also search by name or file type.
In the overview you can also double-click on a file to check whether it is actually the lost file. Quick Look will attempt to preview the file. Then choose a location where you want to restore the recovered files.
All files that were deleted during the review could be restored without any problems. Files that are ‘safely’ deleted (multiple times overwritten) are irretrievably lost and cannot be recovered.
As the time between deletion and recovery process increases, the chances of recovering deleted files decrease. So it is important to take action as soon as possible after deleting important files.
If you have accidentally deleted files from a USB Stick, USB external hard disk or memory card. Then remove the storage medium from the device as soon as possible, install the app and start the recovery process.
Purchase CAT Data Recovery for Mac
CAT Mac Data Recovery is a great app and can certainly limit the damage once important files are deleted. You can buy the app for $ 70 (a license with a duration of 6 months) after that you pay $ 50 per year.
