iTunes 9.2: “The iPhone cannot be synced. A duplicate file name was specified.”

Some users have reported an issue in which iPhones fail to sync with iTunes 9.2. In these cases, sync attempts result in the error message “The iPhone (name) cannot be synced. A duplicate file name was specified.” This problem may be accompanied by duplication of music and other media files.


There are two potential fixes for this issue:

Remove iToner. As noted in our previous report on iTunes 9.2 syncing problems, appears that the presence of Ambrosia Software’ iToner software may cause problems with syncing. Navigate to ~/Library/iTunes/iTunes Plug-insand/Library/iTunes/iTunes Plug-ins (the Library folders inside your user folder and at the root level of your startup drive) and look for a file called iTonerSupport.bundle. Remove it, then restart, and check to see if iPad syncing occurs more quickly.

UPDATE: Several users have now reported that updating to iToner 2.0.6 resolves this issue.

Turn off note syncing. In iTunes, navigate to the info tab and deselect the option to sync notes, then sync your iOS device. You may need to do this each time you sync.

    i couldn’t find the file itoner.bundle, same problem with jason. but while searching for other solutions i moved the sync status box (to get a better view of my web browser) and it disappeared. seems like by moving the status box it completed the sync. tried it afew times and it worked everytime. i noticed that at the top of iTunes, it states that the sync has completed even though the sync box was still running. moved the box and it disappears. not sure if it will help anyone but worth a try

    Am experiencing the same error as Landon. Downgraded Itunes from 9.2 to 9.1. When plugging in 3Gs, iTunes responds: “iPhone cannot be used because it requires version 9.2 or later

    Can anyone please help?

    iTunes 9.2.1(4)

    iToner 2.0.6

    Open iTunes.

    Select your iPhone.

    Under “info” tab deselect “sync notes.” You’ll need to scroll down the page a bit to see this checkbox.

    Sync your iPhone– it should sync OK now.

    Now go back to iTunes and recheck “sync notes” if you want notes to be synced.

    Sync your iPhone again.

    No error message should appear if it works for you like it did for me.

    Good luck!

    @Mike & others:

    I’m fairly certain you cannot revert to previous versions of iTunes if you are syncing with an iPhone. Once updated, I believe you are stuck.

    For more on such issues, try, as these issues are relevant for jailbreakers.

    Good luck.

    My i-pod will not sync…I have updated i-tunes 6 November 2010 and since then nothing will sync and all of my 27gb worth of music files will nto appear on the i-pod!! When trying to reload from library the message ‘the i-pod can not be synced. A duplicate file name was specified’ appears. On settings I am told that 27 GB has been used so the old files are still there, but not accessible to play….HOW DO I RESOLVE THIS ISSUE?
