I intended to use this command:

mklink/J "C:\Users\DELL\Appdata\Roaming\Apple Computer\MobileSync\Backup" "G:\iPhoneBackup"

to directly backup my iPhone to the folder iPhoneBackup on an external hard drive G:. However, when I used the command, it gave a syntax error.

So I used quotation marks around "Apple Computer" like this, which I now realize was incorrect:

mklink/J "C:\Users\DELL\Appdata\Roaming\"Apple Computer"\MobileSync\Backup" "G:\iPhoneBackup"

and noticed the result was not something I wanted. I didn't understand what this had done, it was definitely not what I had intended:

Junction created for C:\Users\DELL\Appdata\Roaming\Apple <<===>> Computer\MobileSync\BackupG:\iPhoneBackup

Now, no matter what modification I make, I get the error Cannot create a file when that file already exists. I tried all the solutions in this Super User thread but nothing works. I still get the same message.

On the other, hand when I'm trying to backup my iPhone according to the original instructions here, I get an error:

iTunes could not back up the iPhone because the iPhone disconnected

Even though my iPhone and the hard disk are both connected to my PC.

I would really appreciate any help to fix this problem.

  • How did the initial command fail? – T Nierath May 21 '18 at 18:39
  • It didn't create a junction between the source Backup folder in C drive and the iPhoneBackup folder in the external G drive. It did create a junction but for some other folder I can't locate. – Sumayyah Hai May 23 '18 at 11:29
  • Weird... the first version should just work. You could try to locate the junction you created maybe check superuser.com/questions/823959/… but that shouldn't affect how iphone backup behaves. – T Nierath May 23 '18 at 13:37
  • I listed all the available junctions on my computer and the one I intended is there... So I'm wondering does is the problem because I manually removed my iPhone backups from the backup folder in explorer, and not from iTunes? – Sumayyah Hai Jun 18 '18 at 16:26
