Tutorial: How to modify iPhone backup directory in Windows? to save space on the C drive
For many students who have a small SSD on their Windows C drive, backing up their iPhone with iTunes becomes a problem because iTunes uses C drive space for backups by default and cannot be changed. So, what to do?
This is done as follows:
- Create a new backup directory outside the C drive, here is D:\MobileSync\Backup as an example.
- Move the files in the original backup file c:\Users\<your name>\AppData\Roaming\Apple Computer\MobileSync\Backup to D:\MobileSync\Backup, which may take a while.
- Open a command prompt (cmd) and type the following command:
MkLink /J "%AppData%\Apple Computer\MobileSync\Backup" "D:\MobileSync\Backup"
In the case of the Windows Store version of iTunes, the following command is required:
MkLink /J "%UserProfile%\Apple\MobileSync\Backup" "D:\MobileSync\Backup"
And for macOS users, it is possible to run the following command in Terminal:
ln -s "/Volumes/<New Volume>/MobileSync/Backup" "/Users/<User>/Library/Application Support/MobileSync"
The New Volume above is the new disk name, which can be seen in the terminal by typing
Note that while this method works for backups of iOS devices, it cannot be used to redirect subfolders of the iTunes Media folder.
