How to Set Up and Use File History Backup on Windows 11 (25H2)

Losing important files — whether from accidental deletion, a hard drive crash, or a corrupted update — can be devastating. Windows 11 (25H2) includes a built-in backup tool called File History that automatically saves copies of your files at regular intervals to an external drive or network location. Once it’s running, you can browse through previous versions and restore exactly what you need, down to a specific date and time.

This guide walks you through every step: enabling File History, customizing which folders are included or excluded, adjusting the backup schedule and retention policy, and restoring files when something goes wrong.

What Is File History?

File History is a Windows backup feature that continuously monitors your personal folders — Documents, Pictures, Music, Videos, Desktop, and more — and saves copies to a connected external drive or a network share every time the contents change (or on a set schedule). Unlike a full system image backup, File History focuses on your personal data, making it fast, lightweight, and easy to use.

Key advantages of File History include:

• Automatic backups — runs in the background without any manual effort after setup
• Version history — keeps multiple dated copies so you can go back to a file from days, weeks, or months ago
• Granular restore — retrieve a single file or an entire folder without restoring a whole system image
• Configurable retention — choose how long old versions are kept, from one month to forever

ℹ Note: File History requires an external USB drive, a second internal drive, or a network-attached storage location. It cannot back up to the same drive where Windows is installed.

How to Enable File History on Windows 11 (25H2)

File History is turned off by default. You need to connect an external drive first, then activate the feature through the Control Panel.

Steps to Enable File History

Step 1: Connect an External Drive

Plug in a USB external hard drive or flash drive with enough free space to hold your backups. Windows 11 will automatically detect it.

Step 2: Open the File History Control Panel

Press Win + S, type File History, and select File History from the search results. This opens the dedicated Control Panel page.

Step 3: Turn On File History

Click the Turn on button on the right side of the screen. Windows immediately begins the first backup and the status changes to show the drive is now active.

Step 4: Change the Drive (Optional)

If multiple drives are connected, click Select drive in the left panel to choose which one File History should use.

Step 5: Verify Backup is Running

After enabling File History, the main page shows the last backup time and a Run now link so you can trigger an immediate backup at any time.

✓ Tip: Keep the external drive connected whenever your PC is in use. File History automatically backs up while the drive is available and skips backups when it’s disconnected.

How to Add Folders to File History

By default, File History backs up all folders in your Windows Libraries (Documents, Pictures, Music, Videos) plus the Desktop and Contacts. To add a folder that’s outside these locations, you need to include it in a Windows Library first.

Step 1: Right-Click the Folder You Want to Add

In File Explorer, navigate to the folder. Right-click it, then hover over Show more options to access the classic context menu.

Step 2: Include in Library

In the expanded context menu, hover over Include in library, then select an existing library such as Documents or Pictures — or create a new library — to add the folder to File History’s backup scope.

✓ Tip: To back up a work project folder or any custom location, create a new library named “Work Projects” and add it — File History will include everything inside automatically.

How to Exclude Folders from File History

If your Libraries contain large subfolders you don’t need backed up (such as downloaded installers or cache files), you can exclude them to save disk space on your backup drive.

Step 1: Open Exclude Folders Settings

In the File History Control Panel, click Exclude folders in the left panel.

Step 2: Click Add

Click the Add button to open a folder browser.

Step 3: Select the Folder to Exclude

Navigate to the folder you want to exclude from backups and click Select Folder.

Step 4: Save Changes

After selecting the folder, it appears in the exclusion list. Click Save changes to apply.

How to Change Backup Frequency and Retention

By default, File History saves copies every hour and keeps them indefinitely. You can adjust both settings from the Advanced settings page to better fit your storage capacity and workflow.

Step 1: Open Advanced Settings

In the File History Control Panel, click Advanced settings in the left panel.

Step 2: Set How Often to Save Copies

Under Save copies of files, click the dropdown to choose a backup frequency: every 10 minutes, 15 minutes, 20 minutes, 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, or daily.

Step 3: Set How Long to Keep Saved Versions

Under Keep saved versions, choose how long backup copies are retained: 1 month, 3 months, 6 months, 9 months, 1 year, 2 years, or forever (the default).

⚠ Warning: Setting Keep saved versions to a short period like 1 month means File History will delete older copies automatically. If you rely on going back further in time, choose a longer retention period or “Until space is needed.”

Step 4: Clean Up Old Versions Manually

If the backup drive is running low on space, click Clean up versions to delete old backups on demand.

Step 5: Choose a Time Period for Cleanup

A dialog asks which versions to delete — all but the latest, versions older than 1 month, 3 months, 6 months, 9 months, 1 year, or 2 years. Select the appropriate option and click Clean up.

Step 6: Save Advanced Settings

After adjusting frequency and retention options, click Save changes to apply your new settings.

✓ Tip: For most home users, backing up every hour and keeping versions for 3–6 months is a good balance between protection and storage usage.

How to Restore Files Using File History

When you need to recover a deleted file or retrieve an earlier version of a document, File History provides a visual timeline browser that makes restoring files straightforward.

Step 1: Open Restore Personal Files

In the File History Control Panel, click Restore personal files in the left panel. This opens the File History restore browser.

Step 2: Browse Through Backup Versions

The restore browser shows your backed-up folders at a specific point in time. Use the left and right arrow buttons at the bottom to navigate backward or forward through backup snapshots by date and time.

Step 3: Select Files and Click Restore

Navigate into the folder, select the file or files you want to recover, then click the green Restore button (the circular arrow icon) at the bottom center of the window.

Step 4: Choose What to Do if the File Already Exists

If a file with the same name already exists in the destination, Windows prompts you to Replace the file in the destination, Skip this file, or Compare info for both files to decide case by case.

✓ Tip: To restore a file without overwriting the current version, choose Compare info for both files and then keep whichever copy has the content you need.

ℹ Note: You can also access previous versions of a specific file directly from File Explorer — right-click the file, select Show more options, then choose Restore previous versions to see all File History snapshots for that file.

Conclusion

File History is one of the most overlooked features in Windows 11, yet it provides dependable, automatic protection for everything in your personal folders. Once you plug in an external drive and click Turn on, your files are continuously backed up in the background without any ongoing effort on your part.

From adding custom folders to your Libraries, to excluding large directories you don’t need, to tweaking how often backups run and how long versions are kept — every aspect of File History is configurable to suit your storage and recovery needs. And when something does go wrong, the visual restore browser makes it easy to step back in time and retrieve exactly what you lost.

Set it up once today, and you’ll never have to worry about accidental file loss again.
