How to Delete iTunes Backup on Windows 10: A Step-by-Step Guide

Have you noticed that your Windows 10 computer is running out of storage space? If you regularly connect your iPhone or iPad to your computer, old iTunes backups could be taking up a significant amount of your hard drive.

iTunes creates backups of your Apple devices so you can restore your photos, messages, settings, application data, and other information if something goes wrong. While these backups are useful, they can eventually consume several gigabytes of storage.

The good news is that you don’t need to keep every old backup forever.

In this guide, we’ll explain how to delete iTunes backup on Windows 10 using simple, step-by-step instructions. You’ll learn how to remove backups through iTunes, find backup folders manually, delete unnecessary files, and free up valuable disk space.

We’ll also cover common problems, explain how to identify the correct backup, and share useful tips to prevent unnecessary backups from filling your computer.

Whether you’re a beginner or an experienced Windows user, this guide will help you manage your iPhone and iPad backup files safely.

Key Takeaways

• You can delete iTunes backups directly through iTunes Preferences.

• The Devices section displays available device backups.

• File Explorer can help you locate iTunes backup folders manually.

• Deleting an iTunes backup permanently removes that local backup.

• You should keep at least one recent backup of important Apple devices.

• Old backups can consume several gigabytes of storage.

• You can use Windows 10 Storage settings to check available disk space.

• Never delete an active or important backup without confirming that you no longer need it.

What Is an iTunes Backup in Windows 10?

An iTunes backup is a saved copy of information from your iPhone, iPad, or compatible Apple device.

When you connect your Apple device to a Windows computer and create a backup through iTunes, the program stores backup data on your computer.

This information can help you restore your device if:

• Your iPhone becomes damaged.

• You accidentally delete important information.

• You purchase a new iPhone.

• You need to restore factory settings.

• Your device experiences software problems.

• You lose information during an iOS update.

Depending on your backup settings and device configuration, iTunes may create multiple backups over time.

What Information Does an iTunes Backup Contain?

An iTunes backup can contain different types of device information.

Common examples include:

• Device settings.

• Messages and message attachments.

• Call history.

• Photos and videos not already synced or stored elsewhere.

• Application data.

• Home screen organization.

• Certain account and configuration information.

• Health and Activity data when using encrypted backups.

Some information, such as content already synchronized with cloud services, may not be included in the local backup.

Why Do iTunes Backups Take Up So Much Space?

Every time you create a backup, iTunes saves device information on your computer.

Although subsequent backups may reuse existing backup data, maintaining multiple device backups can still consume considerable storage.

For example, if you back up multiple iPhones and iPads on the same computer, the total backup folder can become quite large.

Removing backups you no longer need can help recover disk space.

Why Should You Delete Old iTunes Backups?

Before learning the deletion process, let’s understand why removing unnecessary backups can be useful.

1. Free Up Hard Drive Space

Storage space is one of the biggest reasons users delete old iTunes backups.

A backup can occupy several gigabytes, depending on the amount of data stored on your device.

If your computer has a relatively small SSD, these files can quickly reduce available storage.

Deleting unnecessary backups gives you more room for:

• Documents.

• Applications.

• Videos.

• Photos.

• Windows updates.

• Other important files.

2. Remove Backups From Old iPhones

Have you upgraded to a new iPhone?

If you still have backups from your previous device, they may no longer be useful.

Removing outdated backups helps keep your computer organized.

3. Manage Multiple Device Backups

Families sometimes use one computer to back up several Apple devices.

Over time, iTunes may accumulate backups from different iPhones and iPads.

Removing backups from devices you no longer use can simplify backup management.

4. Organize Your Computer

Old backup folders can make it difficult to identify the latest backup.

Cleaning up unnecessary files helps you manage your available backups more efficiently.

5. Resolve Backup Storage Problems

If iTunes cannot create a new backup because your computer has insufficient storage, deleting an old backup may help.

However, make sure you don’t remove the only backup containing important information.

What Should You Check Before Deleting an iTunes Backup?

Before removing a backup, take a few precautions.

Deleting an iTunes backup is generally straightforward, but the action cannot easily be reversed.

1. Identify the Correct Backup

Check which iPhone or iPad created the backup.

If you have multiple Apple devices, make sure you know which backup belongs to each one.

2. Check the Backup Date

Always review the backup date before deleting anything.

A recent backup may contain information that isn’t available anywhere else.

An older backup may be unnecessary if you already have a newer, working backup.

3. Confirm That You Have Another Backup

If your device contains important information, consider keeping another backup.

You can create a new iTunes backup or use a suitable iCloud backup.

Having an alternative provides additional protection.

4. Close Unnecessary Applications

Close iTunes and other unnecessary applications if you plan to delete backup folders manually.

This helps avoid file access conflicts.

5. Check Available Storage

Before and after deleting the backup, check your computer’s available storage.

This helps you confirm whether the cleanup recovered the expected space.

How to Delete iTunes Backup on Windows 10 Using iTunes

The easiest and safest way to remove an iTunes backup is through the iTunes application.

You don’t need to search through hidden folders or manually identify backup files.

Follow these steps.

Step 1: Open iTunes on Windows 10

First, launch iTunes on your computer.

1. Click the Windows Start button.

2. Type iTunes in the search box.

3. Select iTunes from the search results.

4. Wait for the application to open.

If iTunes is already running, you can continue to the next step.

Step 2: Open the Edit Menu

Look at the menu bar at the top of the iTunes window.

Click Edit.

A dropdown menu will appear with several options.

Step 3: Select Preferences

From the Edit menu, select Preferences.

Alternatively, you may be able to open Preferences using the keyboard shortcut:

Ctrl + ,

The Preferences window contains different settings for managing iTunes.

Step 4: Open the Devices Tab

Inside the Preferences window, locate the Devices tab.

Click it.

You should now see a list of device backups stored through iTunes on your computer.

Depending on your backup history, the list may include backups from:

• Your current iPhone.

• Your previous iPhone.

• An iPad.

• Other Apple devices previously backed up using iTunes.

Step 5: Select the Backup You Want to Delete

Review the available backup entries carefully.

Check the device name and backup date.

Select the backup you no longer need.

If multiple backups appear, make sure you select the correct one.

Step 6: Click Delete Backup

After selecting the backup, look for the Delete Backup button.

Click it.

iTunes may display a confirmation message asking whether you want to remove the selected backup.

Step 7: Confirm the Deletion

Click Delete or confirm the action when prompted.

iTunes will remove the selected backup from your computer.

The backup will no longer be available for restoring that device.

Step 8: Close the Preferences Window

After deleting the backup, click OK or close the Preferences window.

You can return to the main iTunes screen.

Step 9: Verify That the Backup Was Removed

To confirm the deletion:

1. Open Edit.

2. Select Preferences.

3. Click Devices.

4. Review the backup list.

The deleted backup should no longer appear.

Congratulations! You’ve successfully deleted an iTunes backup using Windows 10.

How to Delete iTunes Backup Manually Using File Explorer

Sometimes you may prefer to remove backup files manually.

For example, iTunes may not display an old backup, or you may need to investigate how much storage your backup folders occupy.

Windows 10 allows you to locate these folders through File Explorer.

However, manual deletion requires extra care.

Step 1: Close iTunes

Before accessing backup folders, close iTunes.

Make sure it is not actively creating or restoring a backup.

Step 2: Open File Explorer

Press:

Windows + E

This keyboard shortcut opens File Explorer.

Step 3: Open the iTunes Backup Location

For traditional desktop installations of iTunes, the default backup location is commonly:

C:\Users\YourUsername\AppData\Roaming\Apple Computer\MobileSync\Backup

Replace YourUsername with your actual Windows account folder name.

You can also access this location using the Run dialog box.

Press Windows + R and enter:

%APPDATA%\Apple Computer\MobileSync\Backup

Press Enter.

If the folder exists, File Explorer should open the iTunes backup directory.

Step 4: Review the Backup Folders

Inside the Backup folder, you may see one or more folders with long combinations of letters and numbers.

These folders contain backup information for Apple devices.

Their names may not clearly identify the device.

Do not assume that the largest or oldest-looking folder is unnecessary.

Step 5: Identify the Backup Carefully

If you need to identify a backup, use the Devices section in iTunes whenever possible.

You can also examine backup metadata, but avoid changing or removing individual files inside a backup folder.

Step 6: Delete the Unnecessary Backup Folder

Once you have positively identified the backup you no longer need:

1. Select its corresponding backup folder.

2. Right-click the folder.

3. Select Delete.

4. Confirm the deletion if Windows asks.

You can also move the folder to the Recycle Bin instead of permanently deleting it.

Step 7: Empty the Recycle Bin if Appropriate

Deleting a folder normally moves it to the Recycle Bin.

To recover the storage space immediately, you may empty the Recycle Bin.

Remember that emptying it permanently removes the deleted files.

Important: Do not delete the entire MobileSync folder unless you are certain that you no longer need any backups stored there.

How to Find iTunes Backup Location on Windows 10

The backup location can vary depending on how you installed iTunes.

Some users install the traditional desktop version, while others install iTunes through the Microsoft Store.

Here are the common locations.

If one location does not exist, check the other.

Method 1: Find the Backup Folder Using Run

1. Press Windows + R.

2. Enter %APPDATA%\Apple Computer\MobileSync\Backup.

3. Press Enter.

4. Check whether the folder opens.

Method 2: Check the Microsoft Store Location

1. Press Windows + E.

2. Click the address bar.

3. Enter %USERPROFILE%\Apple\MobileSync\Backup.

4. Press Enter.

If your backup folder exists there, you can inspect its contents.

Method 3: Use Windows Search

You can also search for the MobileSync folder.

1. Open File Explorer.

2. Select This PC.

3. Enter MobileSync in the search box.

4. Wait for Windows to search.

5. Review the matching folders.

This method may take longer, particularly if your computer has several drives.

How to Delete All iTunes Backups on Windows 10

Do you want to remove every old iTunes backup instead of deleting them individually?

You can do this through iTunes or File Explorer.

However, deleting all backups is a significant action.

Make sure you have another copy of any important device information before proceeding.

Method 1: Remove Backups Through iTunes

1. Open iTunes.

2. Click Edit.

3. Select Preferences.

4. Open the Devices tab.

5. Review the available backups.

6. Select an unnecessary backup.

7. Click Delete Backup.

8. Confirm the deletion.

9. Repeat the process for other backups you want to remove.

This approach allows you to review individual backups before removing them.

Method 2: Delete the Backup Folder

You can also remove the entire Backup folder manually.

1. Close iTunes.

2. Open File Explorer.

3. Navigate to the appropriate MobileSync backup location.

4. Confirm that the folder contains only backups you intend to remove.

5. Delete the Backup folder.

6. Empty the Recycle Bin if you want to recover the storage space immediately.

Warning: This removes all local backups contained in that folder. Do not use this method if you want to keep any of them.

How to Check How Much Space iTunes Backups Are Using

Before deleting backups, you may want to know how much storage they occupy.

Windows 10 makes it easy to check folder sizes.

Step 1: Open File Explorer

Press Windows + E.

Step 2: Find the Backup Folder

Navigate to the appropriate MobileSync backup location.

Step 3: Open Folder Properties

Right-click the Backup folder.

Select Properties.

Step 4: Review the Folder Size

Windows will calculate the folder’s total size.

You should see information such as:

• Size.

• Size on disk.

• Number of files.

• Number of folders.

This information helps you understand how much storage the backup files consume.

Step 5: Decide Which Backups to Remove

If you discover that old backups occupy several gigabytes, review them through iTunes and remove the ones you no longer need.

What Happens When You Delete an iTunes Backup?

Deleting a backup removes the saved copy of your Apple device information from that computer.

It does not normally delete the corresponding data from your iPhone or iPad.

For example, if you delete an iPhone backup from your Windows 10 computer, the photos and messages currently stored on your iPhone should remain on the device.

However, you will no longer be able to restore that particular local backup through iTunes.

Here’s a quick overview.

The distinction is important: deleting a computer backup is different from deleting information stored on your Apple device.

How to Free Up More Storage After Deleting iTunes Backups

Removing iTunes backups is one way to recover storage space.

However, you can also use other Windows 10 cleanup options.

1. Delete Temporary Windows Files

Temporary files can accumulate over time.

1. Open Settings.

2. Select Apps.

3. Click Apps & features.

4. Find an application you no longer use.

5. Select it.

6. Click Uninstall.

Follow the instructions to complete removal.

3. Remove Old Downloaded Files

Your Downloads folder may contain unnecessary installers, documents, and media files.

Open File Explorer, select Downloads, and review its contents.

Delete only files you no longer need.

4. Use Disk Cleanup

Windows 10 includes a utility called Disk Cleanup.

To open it:

1. Click Start.

2. Search for Disk Cleanup.

3. Open the application.

4. Select your Windows drive.

5. Review the cleanup categories.

Common Problems When Deleting iTunes Backups and How to Fix Them

Sometimes you may encounter problems while trying to remove backup files.

Let’s look at common issues and their solutions.

Problem 1: Delete Backup Button Is Greyed Out

If the Delete Backup button is unavailable, check whether you have selected a backup in the Devices list.

Try these steps:

1. Open iTunes Preferences.

2. Select Devices.

3. Click an available backup entry.

4. Check whether Delete Backup becomes available.

If the list is empty, there may be no backups available for iTunes to delete.

Problem 2: iTunes Does Not Show Any Backups

If you know that backup files exist but iTunes does not display them, check the installation type and backup location.

Try opening:

%APPDATA%\Apple Computer\MobileSync\Backup

Also check:

%USERPROFILE%\Apple\MobileSync\Backup

The backup may be stored in a different location or may not be recognized by the current iTunes installation.

Problem 3: Windows Says the Folder Is in Use

If Windows refuses to delete a backup folder because it is being used:

• Close iTunes.

• Close Apple-related background applications.

• Make sure no backup or restore process is running.

• Restart your computer.

• Try deleting the folder again.

Do not force deletion while iTunes is actively writing backup files.

Problem 4: Access Is Denied When Deleting a Backup

An access-denied message may appear because of folder permissions.

Try the following:

1. Close iTunes.

2. Right-click File Explorer and check your account permissions.

3. Make sure you are signed in with an account that has permission to manage the folder.

4. Try again.

Avoid changing advanced folder permissions unless necessary.

Problem 5: Deleting a Backup Does Not Free Up Storage

If your available storage does not increase immediately:

1. Check whether the backup was moved to the Recycle Bin.

2. Empty the Recycle Bin if you are sure you do not need the files.

3. Recheck the available disk space.

4. Restart File Explorer or Windows if the displayed storage information has not refreshed.

Also remember that folder size and actual reclaimed disk space may differ.

Problem 6: The MobileSync Folder Is Missing

If you cannot find the MobileSync folder, it may mean that:

• You have not created a local iTunes backup.

• iTunes is installed through a different distribution.

• The backup folder is stored elsewhere.

• The backup folder was previously deleted.

Check both common backup locations before assuming the files are missing.

Should You Delete Old iTunes Backups or Keep Them?

The answer depends on your backup requirements.

If you have already transferred everything to a new iPhone and verified that your important information is safe, old backups may no longer be necessary.

However, keeping a recent backup is generally a good idea.

Consider the following recommendations:

A good backup strategy is better than deleting everything simply to free up storage.
