Spotlight - DearMob iPhone Manager vs. iTunes

Reported by many that piles of iTunes sync error messages are related to "Duplicate File Name Specified", see below:

  • -"A duplicate file name was specified, can't connect to Apple ID"
  • -"The iPhone (name) cannot be synced. A duplicate file name was specified."
  • -"Cannot put songs on iPhone, Duplicate File Name Specified"
  • -"Attempting to copy to the disk 'XX' failed. A duplicate file name was specified"
iTunes says "a duplicate file name was specified"

They seem to be different troubles, but all share the same cause - "Duplicate File Name Specified". Then, how to define which file name is duplicated? And why does this error message come out?

Possible meanings and reasons:

1.If what you are doing is one-on-one device syncing with iTunes, it is highly possible that it is either your iTunes compatibility issue or iTunes library corrupted/duplicated issue that caused the duplicate file name issue.

2.Unknown iTunes errors which may be solved by uninstalling & reinstalling iTunes all Apple components.

3.And if you are doing an iTunes backup/syncing of multiple devices -backing up both iPhone and iPad with duplicated filename, it is possible that you’ve messed up your backup with the other device. You might consider backing up or syncing your other device using a different backup tool.
