iTunes Backup Location: Where iPhone Backups Are Stored

Your iPhone, iPad, or iPod touch backups created through iTunes (or Finder on macOS Catalina and later) are stored in a specific folder on your computer. On Windows, the default location is %APPDATA%\Apple Computer\MobileSync\Backup, and on macOS it is ~/Library/Application Support/MobileSync/Backup. This article explains exactly where those backups live, how to find them, how to move or copy them, and how to troubleshoot common backup location issues.

Why the Backup Location Matters

Knowing where your iTunes backups are stored is useful for several reasons. If you want to free up disk space, you need to know which folder to clean. If you are migrating to a new computer, you need to copy that folder to keep your backups. If you are troubleshooting a failed restore, you may need to verify the backup file exists and is not corrupted. The backup folder is also where you might find old backups from previous devices, and understanding its structure helps you manage them safely.

Default Backup Locations by Operating System

The exact path depends on your operating system and whether you are using iTunes or the newer Finder-based backup method on macOS.

• Windows 10 and 11 (iTunes from Microsoft Store): %APPDATA%\Apple Computer\MobileSync\Backup — this expands to C:\Users\[YourUsername]\AppData\Roaming\Apple Computer\MobileSync\Backup
• Windows 7, 8, and 8.1 (iTunes from Apple): %APPDATA%\Apple Computer\MobileSync\Backup — same path as above, but the %APPDATA% variable points to C:\Users\[YourUsername]\AppData\Roaming.
• macOS Catalina and later (Finder): ~/Library/Application Support/MobileSync/Backup — the tilde (~) is your home folder, so the full path is /Users/[YourUsername]/Library/Application Support/MobileSync/Backup.
• macOS Mojave and earlier (iTunes): Same path as above, ~/Library/Application Support/MobileSync/Backup.

Note that on Windows, the %APPDATA% environment variable is hidden by default. You may need to enable “Show hidden files and folders” in File Explorer to see the AppData folder.

How to Find Your Backups in iTunes or Finder

Instead of manually navigating to the folder, you can use the built-in interface to see your backups and their locations.

1. On Windows (iTunes): Open iTunes, click Edit in the menu bar (or press Ctrl+B to show the menu bar if hidden), then go to Preferences > Devices. You will see a list of all backups with their dates and times. To reveal the backup in File Explorer, right-click the backup name and select Show in Windows Explorer.
2. On macOS (Finder): Connect your device, open Finder, and select your device under Locations. In the General tab, you will see a Manage Backups button. Click it to see a list of backups. Right-click (or Control-click) a backup and choose Show in Finder to reveal the actual folder.
3. On macOS (iTunes for older systems): Open iTunes, go to Preferences > Devices, right-click a backup, and select Show in Finder.

This method is the safest way to locate the exact backup folder, because the folder name is a long hexadecimal string (like 00008110-001D1E1A3A38001E) that is not human-readable.

What’s Inside the Backup Folder

Each backup is stored in its own subfolder named with a unique device ID (a 40-character hexadecimal string). Inside that folder, you will find:

• Manifest.plist — a property list file that contains metadata about the backup, including the device name, iOS version, and backup creation date.
• Info.plist — contains device information such as the serial number, phone number (if applicable), and product type.
• Status.plist — indicates whether the backup is complete or in progress.
• Many small files and folders — these are the actual app data, photos, messages, and settings, stored in a proprietary format. You cannot read them directly; they are only usable by iTunes/Finder for restore purposes.

If you see multiple folders, each one corresponds to a different device. To identify which folder belongs to which device, you can open the Info.plist file with a text editor (like Notepad or TextEdit) and look for the Device Name key.

How to Change the Backup Location

By default, backups are stored on your system drive (usually C: on Windows, or the Macintosh HD on macOS). If you are running low on space, you might want to move the backup folder to an external drive or a different partition. Apple does not provide a built-in setting to change the backup location, but you can do it manually by creating a symbolic link (symlink) that redirects the original folder to a new location.

On Windows (using Command Prompt as Administrator):

1. Quit iTunes.
2. Move the entire Backup folder to your desired location, for example, D:\iTunesBackups\Backup.
3. Open Command Prompt as Administrator.
4. Run the following command to create a symbolic link:
   mklink /J "%APPDATA%\Apple Computer\MobileSync\Backup" "D:\iTunesBackups\Backup"

On macOS (using Terminal):

1. Quit Finder (the backup service) and iTunes if open.
2. Move the Backup folder to your desired location, for example, /Volumes/ExternalDrive/MobileSync/Backup.
3. Open Terminal and run:
   ln -s /Volumes/ExternalDrive/MobileSync/Backup ~/Library/Application\ Support/MobileSync/Backup

After creating the symlink, iTunes/Finder will still look in the original location, but the files are actually stored on the new drive. Be careful when doing this — if you delete the symlink, you might lose access to your backups. Always keep a copy of the original folder until you are sure the symlink works.

Common Problems and Solutions

Users often encounter issues related to backup location. Here are the most frequent ones and how to fix them:

• Backup folder not visible: On Windows, the AppData folder is hidden by default. Open File Explorer, go to View > Options > Change folder and search options, then under the View tab, select Show hidden files, folders, and drives.
• Backup folder is empty or missing: If you have never backed up to this computer, the folder may not exist yet. Connect your device and create a backup first. If it still does not appear, check if you are looking at the correct user account — backups are per-user.
• “Not enough space” error during backup: This usually means the backup location drive is full. Free up space or move the backup folder to a larger drive using the symlink method above.
• Cannot restore because backup is corrupted: If a backup fails to restore, the folder might be incomplete. Delete the specific backup folder and create a new backup. Do not delete all backups unless you are sure you do not need them.
• Backup folder is on a network drive: iTunes/Finder does not support network drives for backups. You must use a local disk or a directly attached external drive.

Backing Up Your Backups: Copying and Moving

If you want to transfer your backups to a new computer, you can simply copy the entire Backup folder to the same location on the new computer. For example, copy C:\Users\[Username]\AppData\Roaming\Apple Computer\MobileSync\Backup to the same path on the new PC. On macOS, copy ~/Library/Application Support/MobileSync/Backup to the same location on the new Mac. After copying, open iTunes/Finder and you should see the backups listed in Preferences > Devices.

When copying, make sure you do not interrupt the process — a partial copy will be unusable. It is also a good idea to verify the destination folder has enough free space before starting.

Frequently Asked Questions

Can I open an iTunes backup to view my photos or messages?

No. The backup files are stored in a proprietary binary format that is not meant to be read directly. You can only restore them to an iOS device using iTunes or Finder. There are third-party tools that claim to extract data, but they are not officially supported and may not work with the latest iOS versions.

Why is my backup folder so large?

Backups contain almost everything on your device, including photos, videos, messages, app data, and settings. If you have many high-resolution photos or large apps, the backup can be several gigabytes. You can reduce the size by excluding certain apps from the backup (in iTunes/Finder, go to your device’s File Sharing section and uncheck apps you don’t need backed up), but this is not always possible for system data.

Does iCloud backup use the same folder?

No. iCloud backups are stored in Apple’s cloud servers, not on your computer. The local backup folder we discussed is for backups made via iTunes or Finder. If you use both, you will have two separate backups — one local and one in iCloud.

How do I delete old backups to free up space?

In iTunes/Finder, go to Preferences > Devices, select the backup you want to delete, and click Delete Backup. You can also manually delete the corresponding folder in the backup directory, but using the interface is safer because it ensures the backup is properly removed from the system index.

What happens if I delete the backup folder manually?

If you delete the entire Backup folder, all your local backups will be lost. The next time you back up your device, a new folder will be created. If you delete only a specific device’s subfolder, that device’s backup will be gone. Always confirm you do not need the backup before deleting.
