Have you ever thought that recovering all your deleted files is a myth? Yes, you can indeed get your lost files back under certain circumstances. On the contrary, you might permanently lose it at your wits' end. Hopping on Google, you’ll see scores of software that promise to get all your deleted data back. But here’s one question you should ask yourself: How does data recovery software work? Is it magic? This simple guide has the answer to all your confusion.

What Happens When You Delete A File?

Deleted files can be quite sneaky. Even if you delete them from your hard drive, they are still stored somewhere in the drive. For example, even if you empty your Recycle Bin, the files don’t go anywhere because they are still not physically erased from the hard drive.

Look at your computer. Do you see all those files? Well, they’re all made up of infinite, tiny pieces of digits. When you perform the deletion, those bits aren’t erased along with the file. They are still kept intact on your personal computer.

Completely deleting files is a process that takes a significantly longer period to execute. The "0" and "1" that make up the file will hide until they are overwritten with another file. And you need to know that when you delete a file, your operating system will simply mark the deleted files as free or blank space.

  • OS(Windows, macOS, Ubuntu) gives the files a pointer to identify the location.
  • Users delete a file, OS removes the pointer and marks it as free space.
  • OS leaves the file content untouched until new files cover the free space.

How to Recover Deleted Files from Your Hard Drives?

So, do you understand how data recovery software or service work? Your operating system just marks them as free space, which makes it possible to recover them. And you will need third-party data recovery software or tools, which were developed to find the deleted data on your hard drives and then relocate their pointers.

Step 2 Scan The Hard Disk

When Recoverit scans the storage partition, you can use filter tools to narrow the range. For example, choose file size and file type will help reduce scanning time.

Why Some Deleted Files Can Be Recovered While Others Cannot

Sometimes, even the most efficient software can’t recover your files because it’s simply NOT POSSIBLE. If your Windows or Mac OS writes new data to the space that a deleted file once occupied, you can’t do anything but say "farewell" to the original file because it can’t be restored anymore. Why? The content of the original file doesn’t exist anymore because it has been overwritten by the new information.
