3 Effective Tips to Recover Deleted Files on Mac OS

As the Hierarchical File System (HFS) on Mac is different from New Technology File System (NTFS) on Windows, the ways to recover deleted files are different too. This article will look at the accidentally deleted files in Mac OS to offer you 3 tricks.

On Windows-based computers, if you delete any files by accidentally, it will be far easier to recover the deleted files than recovering on Mac OS. It stems from their different file system. Windows usually use the NTFS file system, whereas the Mac applies Hierarchical File System (HFS). On Mac OS, if you delete a file, the catalog file, which is storing the records for the deleted file and its directory on volume, will get overwritten very soon. Hence, it is a bit more difficult to recover deleted files in Mac OS. Here we will teach you 3 tips to attempt a recovery when deleting any files mistakenly.

Recover Deleted Files on Mac OS

Tip 1: Restore from Mac Trash

In general, the files which you set to be deleted are simply moved to the Trash on your Mac, which is similar to the Recycle Bin in Windows. The trash will store the files until you select to delete them permanently. Therefore, when you realize you have deleted any files mistakenly, you can first look in Trash to check whether the deleted files are over there. If find them in Trash, right click on them and choose “Put Back”. But if not, you have to use the following methods.

Tip 2: Check Mac Time Machine

Without any doubts, if you have data backups, restoring deleted files will be very easy. For instance, if you’ve backed up PST data, you will be able to recover PST data from backups with utmost ease after Outlook corruption. Hence, you should attach great importance to data backups. Fortunately, Mac OS comes pre-installed with backup feature – Time Machine, which can create incremental backups for Mac data. Like other data backup software, it can back up Mac data to an external data storage device, such as an external hard drive or Mac OS Server on network. Hence, now that you’ve had data backups, you can directly recover the deleted files from the Time Machine.

Tip 3: Attempt Logical Mac Data Recovery

If both of the above two means are helpful for you, you have no choice but to try a logical Mac data recovery. You can resort to related recovery software or recur to the experts. The most common logical Mac data recovery is using the journal files in Hierarchical File System (HFS). Generally speaking, the recovery process will go through the following 5 steps:

  1. Firstly, get access to the volume header.
  2. Then utilize the volume header to locate the journal file.
  3. Next analyze the journal file.
  4. Subsequently, identify and analyze the corresponding catalog files.
  5. Once find the records of the deleted files, data recovery can start.
