File History is one of the most useful features built into Windows, and also one of the least known. Once you turn it on, it quietly saves copies of your documents, pictures, and other personal files to an external drive or network location, again and again, without you doing anything.
That means if you delete a file by accident, save over an important document, or your laptop drive fails, you can go back to an earlier version instead of losing the work forever.
This guide shows you exactly how to set up File History on Windows 10 and Windows 11, choose what it backs up and how often, and confirm that it is working.
Quick Answer
To set up File History, connect an external drive, open Settings, search for File History or backup settings, select the drive, and turn File History on so it backs up your documents automatically. Set it to run every hour and keep saved versions for as long as space allows, or for at least three to six months. Run the first backup immediately and check that copies appear on the drive.
What File History Backs Up
By default, File History protects the files in your main user folders: Documents, Desktop, Pictures, Music, Videos, Downloads, and other folders inside your user profile, including files stored in libraries.
It does not make a copy of Windows itself or your installed programs. It is a file backup, designed for the documents and media you create and change every day. For a complete copy of the whole system, you need a system image as well, which is a separate job explained in our guide to backing up your entire Windows PC to an external drive.
The special strength of File History is versions. If it runs every hour, it can keep several versions of the same document from different times, so you can recover the draft from Tuesday morning, not just the latest copy from Friday.
What You Need
- A Windows 10 or Windows 11 PC with your files in the usual user folders, or in folders you can add to a library.
- An external USB drive with enough free space. At least double the size of the files you protect is a good starting point.
- Or a network drive or shared folder, if you prefer to back up to another computer or a home storage device.
- About fifteen minutes for setup, plus time for the first full copy to finish.
The drive will be used regularly, so choose one you can leave connected to a desktop PC, or remember to plug into a laptop at least once a day.
Step-by-Step: Turn On File History
- Connect the external drive and wait until it appears in File Explorer.
- Open Settings by pressing Windows key + I.
- Search for “File History”. In Windows 11, the search in Settings or the Start menu will lead you to the classic File History control panel. In Windows 10, you can also go to Settings, Update & Security, Backup.
- Select “Add a drive” or “Select drive” and choose your external drive from the list.
- Turn File History on. Use the switch that says to automatically back up your files, or the Turn on button in the classic panel.
- Select “More options” or “Advanced settings” to control how often it runs and how long versions are kept, as explained in the next section.
- Select “Back up now” to start the first backup immediately instead of waiting for the next scheduled run.
- Wait for the first backup to finish. Keep the drive connected and the PC awake until the status stops showing that files are being copied.
Microsoft’s own overview is in its guide to backing up a Windows PC, which explains where File History fits alongside cloud backup options.
Choosing How Often and How Long to Keep Versions
Backup Frequency
The default of every hour suits most people who work on documents during the day. If you edit all day and losing an hour would hurt, choose every 10, 15, or 30 minutes. If you only want a lighter backup, daily is acceptable, but remember that anything created and lost between runs will not be recoverable.
Retention: How Long Versions Are Kept
“Forever” or “until space is needed” makes the best use of a large drive, because File History will remove the oldest versions first when space runs low. If your drive is small, choose three or six months so the drive does not fill suddenly and stop the backup without you noticing.
Whichever you pick, check the drive’s free space once a month. A full backup drive is the most common silent reason File History stops protecting people.
Adding or Excluding Folders
In the backup options you can add folders that live outside the default list, such as a work projects folder on a second drive. Select the option to add a folder, browse to it, and confirm it appears in the list of folders being backed up.
You can also exclude folders you do not need, such as a huge downloads folder full of installers you can fetch again. Excluding unimportant bulk keeps the backup faster and leaves more room for versions of the files that really matter.
Be careful with exclusions. If you are unsure whether a folder matters, leave it included. Storage is cheap compared with rebuilding lost work.
How to Confirm File History Is Working
Do not trust the on switch alone. After the first backup, open the external drive in File Explorer. You should see a FileHistory folder containing your user name, the computer name, and copies of your files in a Data folder.
Open one or two copied documents from the drive to confirm they are real and readable. Then, in the File History settings, check the date and time of the last successful run. If that time updates on schedule over the next few days, your automatic backup is doing its job.
Common Mistakes and Helpful Tips
- Unplugging the drive and forgetting it. File History can only run when the drive is connected. Laptop users should build a habit, such as plugging in the drive whenever the laptop is charging at the desk.
- Backing up to the same internal drive. File History needs a separate drive or network location. A copy on the same physical drive is lost if that drive fails.
- Assuming OneDrive folders are fully covered in the same way. Cloud-synced folders have their own version history and recycle bin. Understand which protection applies to each folder to avoid a false sense of safety.
- Ignoring a drive letter change. If the external drive gets a different letter and backups stop, reselect the drive in File History settings.
- Never restoring anything as a test. Practise recovering one unimportant file now, so you are not learning the steps during a real emergency.
For the official restore steps, see Microsoft’s guide to restoring files with File History after you have finished the setup here.
Conclusion
Setting up File History takes only a few minutes, and after that Windows looks after your documents automatically. Connect a drive, turn File History on, choose hourly backups, keep versions for several months, and run the first backup straight away.
Check the last backup time and the drive space once a month, and test a restore now and then. With that small routine in place, a deleted file or a failed drive becomes a short delay instead of a permanent loss.
Frequently Asked Questions
Does File History work on Windows 11?
Yes. File History is still included in Windows 11, although you reach it through search or the classic Control Panel rather than a prominent switch in the new Settings app. Once it is on, it works in the same way as on Windows 10.
Can File History back up to a USB flash drive?
It can, but a flash drive is usually too small and too easy to lose for a serious backup. An external hard drive or SSD with much more space is a better choice for keeping many versions over months.
What happens if I unplug the backup drive?
File History pauses and keeps a temporary cache on the PC for a limited amount of changes. When you reconnect the drive, it copies the waiting changes. If the drive stays disconnected for a long time, some versions may never be saved, so reconnect it daily if you can.
Does File History replace cloud backup?
No. File History protects you at home, but the drive sits next to the PC, so fire or theft can take both. A cloud copy in a different place is a valuable second layer for your most important files.
How do I stop File History or change drives?
Open File History settings, turn it off, and if you are changing drives, select the new drive and turn it back on. Your old copies stay on the old drive until you delete them, so nothing is lost during the switch.
