How to Recover Overwritten Files on Windows Additionally, if you’ve lost your data, avoid using the drive until you’re in a position to perform recovery, as regular use can cause your data to be overwritten with temporary system files. When moving data around your drive, make sure every file has a unique filename so none of your files overwrite each other.

However, once an existing file is overwritten, or a new file is written to the same physical space as your deleted file, recovery becomes extremely unlikely given the contents of the file have been replaced. This allows data recovery tools to scan your drive and recover this data. Until new data is written to that same physical location, your data will still be there. Then, the physical location where your data resided on the drive is marked as available so new data can be written to it. Instead, the information that your operating system uses to locate that file is deleted instead. When you delete a file, it’s not actually deleted from your drive immediately. In this article, we are going to describe three of them - two unique to Windows and Mac OS X and one that works on both operating systems. Luckily, there are several ways how you can get it back in just a few minutes.

Sure, Word or Excel will ask you if you are 100% sure about overwriting the original document, but before your brain can stop your fingers from hitting the enter key, the original file is usually gone. It happens to all of us, and all it takes are two identical file names.
