Deleted Mac file recovery used to be done by reading the file system on the disk. If it were a Mac OS disk for example, then the file system would be interpreted by the software, and an analysis would be made to try to determine what data was previously present before the deletion was performed on the file system. In this way, each different file system would be developed for and interpreted in its own individual way, and each file system would have its own success rates and caveats. The success or failure of the file recovery attempt was also generally based on the state of the file system at the time. If the file system had been heavily modified after the file deletion had taken place, then there would be less chances of being able to undo that deletion. Likewise if the file system was heavily corrupted or if it had been formatted, that would often mean that no file recovery would be possible.
If you own a Mac, you already know how great and user-friendly the Mac is when compared to other operating systems. However, there could be times when you run into problems even with your Mac. Accidently deleting important files and emptying your Trash Bin could be one of them. Fortunately, you can still recover your lost files provided you act quickly.
How can a deleted file be recovery?
When you empty your Trash Bin, the Mac operating system does not physically erase the data from the face of the hard disc. The system just erases the file index data that tells the computer where the file is located on the hard drive. It is analogous to going through the table of contents in a book and erasing the page number information that is associated with a particular chapter. So when you look at the table of contents, you would not know which page to turn to since that information is missing, even though the pages are still intact in the book. Likewise, when you empty the Trash Bin, the information about the physical locations of all the files in the Trash Bin are lost.
Even though the files are still intact on the hard drive, the computer no longer has the information to directly access them. In a sense, the computer disowns these files and ignores them as they are no longer useful to the user. However, there are specialized software applications that can scan through the hard drive and find these orphaned files and retrieve them fully or at least partially.
Precautions for Lost/Deleted Word Documents and file on Mac
How much of the word document recovery depends on a few crucial factors. You need to understand that even though a file that is orphaned stays intact on the hard drive, it can be eventually lost if left unattended for a long time. This is because the area occupied by a lost file is now available for use to the computer. If the computer needs space to store a new file, it may utilize this space occupied by the lost file to store the new file. In other words, the lost file can be overwritten by the contents of the new file. In effect, you would
lose all the information stored in the lost file.
