It will also introduce a top free data recovery software (MiniTool Power Data Recovery) and a stellar data backup program (MiniTool ShadowMaker) to help you protect your data and avoid data loss.

Obstacles and Chances to Recover Overwritten Files

Let’s first know something about data overwriting and figure out the differences between file deleting and file overwriting.

What Happens When You Delete a File

If you deleted a file on your computer, it will go to the Recycle Bin first. If you also emptied the Recycle Bin, you can still easily recover the file with a data recovery software program. This is because the file is not really gone and it is still existed on your computer.

Windows tracks files on the hard drive using pointers. It uses pointer to mark the beginning and ending of each file or folder. When you delete a file, your computer just marks the file is no longer needed and marks the sectors containing the file’s data as available. The actual file content is untouched.

When you try to store new files to your computer hard drive, the operating system may write new data over the old data since the sectors of old deleted files are marked as vacant. And this will delete the old files terminally.

About Data Overwriting Process

Data overwriting is the process of replacing old data with new data. If your computer has unused file system clusters, or you delete some old files on your computer and released some file system clusters, the unused/released file system clusters might be overwritten when you store new data into your computer.

If you replace a file by another file with the same name, it will also cause data overwriting. The overwritten/replaced files don’t go to the Recycle Bin.

In a word, a deleted file is logically removed from computer system while an overwritten file is physically changed. The deleted file can be easily recovered with data recovery software while the overwritten file is hard to restore even with professional data recovery program.

Chances to Recover Overwritten Files

As for the chances to recover old files after overwriting, it depends on whether and how much the spaces of old files are occupied by newly overwritten data.

If the newly stored file only occupies partial of the sectors of old data, you might get back a certain percentage of your lost/deleted data. But there is a possibility that the restored file is broken. However, if the newly stored file is larger than the older file and takes all space of the old file, then it’s unlikely to recover the lost files with best data recovery software. Even if you may see your old file after file recovery, it may be corrupted or inaccessible.

And this is why it’s recommended that you stop using the device which contains lost or deleted files and don’t store new data into it.

Anyway, unless you totally erase or wipe the hard drive, external hard drive, USB, SD card, you can still try to use a reliable powerful data recovery software to get back the old overwritten Word documents, Excel files, photos, videos, etc. from them. If you are lucky enough, you may retrieve your lost file.
