iTunes Library file cannot be saved. A duplicate file name was specified.

Best guess from the info. provided is that your anti-virus program is holding up iTunes when it wants to write out files, causing it to have another go by which time the AV has "let go" of the suspended file operation. Try to exclude the iTunes folder from AV scanning.

If that's not it, more details would be handy for aiding diagnosis. E.g. computer brand/model, (VIAO's are notorious for interfering 3rd party software), which AV package, any other symptoms etc.

Check the security permissions for your iTunes folder. Your account (or everyone) and system should have full access to the iTunes folder and all files and subfolders below it. If your drive has moved from one system to another you may need to "take ownership" of the drive before you can modify the permissions.

Hi There, i have some issue for months now. can you tell me how to search for teh duplicate . tmp file and delete it.

I also have the same problem as in the duplicate file was specified thing after opening up itunes.

But for me is the apps. I can't download or update my apps from my comp but i can do that on my iphone. I did tried to transfer purchases but it popped up about something that if i dont authorize this comp my apps will be removed. When i clicked dont authorize, it removed almost all my apps so i stopped in the middle of syncing. I click authorize and after entering my apple ID, another pop up saying that there is an error in transfering the purchases and told me to repair my itunes. I tried that too but it didnt work. I already did authorize my comp long ago. When i clicked cancel, it doesnt sync all my stuff and remains the same cause it always stuck at the apps. I tried to uninstall itunes but it says there's an error in the package thing, error code 2330. Any idea on what should i do? >_<
