HFS+ file system is an exclusive file system developed by Apple and is mainly used on Macintosh. A drive which has HFS+ file system is called HFS+ drive. Compared with HFS file system, HFS+ file system has changed the way how information is stored and maintained, and can be more reliable.
But HFS+ file system can't be 100 percent safe - we may mistakenly delete a single file or plenty of files, empty Mac Trash without realizing some of the files are still useful, or fail to find the deleted file in Mac Trash and Time Machine. No matter the above operations are done with intention or without intention, we will lose those files.
About HFS+ deleted file recovery
When we delete a file on HFS+ drive, the macOS will only delete the directory entry, while the real data still exists at the drive but is been hidden and the space of the deleted file becomes available for new data. Compared with other file systems (like FAT32, exFAT, and NTFS), one significant feature of HFS+ file system is that when a file is deleted in HFS+ drive, its directory entry will be write to the journal file, similar to back up the directory entry.
