How did my file get overwritten?

Files can be overwritten for a number of reasons, and in some cases, the circumstances can determine whether or not the original file will be recoverable at all.

Human error

Let’s be honest, files don’t overwrite themselves. If a file has been saved over, there’s a pretty good chance that it’s the result of human error in some shape or form.

Here are just a few examples of common mistakes that could lead to a file being overwritten:

  • You’ve gone to save a new file and accidentally clicked on an existing file before hitting Save.
  • You meant to overwrite a file with a new version, but clicked on the wrong one.
  • You returned to a file, made some changes, and then saved the file—either accidentally or intentionally. It might be that you were just experimenting, such as trying some changes to a digital illustration or video edit, and didn’t mean to overwrite your original copy.

File deletion and overwriting of storage space

In addition to manually saving over a version of a file, the term “overwriting” can also refer to the overwriting of the storage space itself.

When a file is deleted, it’s often not actually removed from the computer’s internal hard drive. Rather, the location on the hard drive where the file was stored is marked as available for overwriting with new data. Once that new data is stored to the same location, recovery of the original overwritten data becomes much more difficult.

Luckily, recovering files that have been overwritten due to human error can be quite simple.

How to recover overwritten files on a Windows PC

In order to recover an overwritten file that was saved locally on your Windows PC, you’ll need to have had the File History feature enabled.

Once that’s confirmed, simply follow these steps to recover your file:

  1. Open Windows Explorer and open the folder that contained the overwritten file.
  2. From anywhere within the folder, right-click and select Properties.
  3. Select the Previous Versions tab.
  4. Look at the list of versions, each with a date, and find the version you want.
  5. Select the version you’d like to restore.
  6. Click Restore.

How to recover overwritten files on a Mac

File recovery on Mac devices is much simpler than their Windows counterparts, thanks to built-in systems on MacOS.

Providing the Time Machine feature has been enabled, recovering overwritten files is simple:

  1. Open Time Machine.
  2. Navigate to the folder containing the file.
  3. Select the version of the file you want to recover from the Time Machine vault.
  4. Click Restore.

What to do next: Backup your system for quick and easy file recovery

Discovering that you’ve overwritten a file and then figuring out how to recover it is a grueling task that most would prefer not to go through more than once. And if you’re working offline, recovering lost files can be even more complicated.

FAQs about file recovery

Yes—you can recover a previous version of an overwritten file using the File History feature in Windows, or the Time Machine tool in macOS, if they’ve already been enabled on your device. Otherwise, Dropbox Backup is a cloud-based solution that can help to avoid future file loss, giving you more ways to recover files and folders than your device’s built-in local backup features.

You can recover overwritten video files in the same way you would for any other type of file, using File History on Windows devices, or Time Machine on macOS.

Unfortunately, the Ctrl+Z undo shortcut doesn’t work in Windows File Explorer, nor does the Cmd+Z equivalent in Finder on a Mac. To restore the lost data in a previous version of an overwritten file, you’ll need to have had the respective File History or Time Machine feature enabled in advance.
