iOS device owners experiencing problems when attempting to sync with a Windows PC may find a resolution to their woes in a new Support document from Apple.

Apple acknowledges that some users syncing an iPhone, iPad, or iPod touch with a Windows computer may see one or more of the following alerts:

· "The [device] could not be synced. A folder was specified instead of a file." · "The contents of the iPhone could not be read. You must restore the iPhone" · The "Set up your iPhone" prompts may reappear after each time you reconnect the device, even after fully setting up the device's sync options.

According to the Cupertino, Calif.-based tech giant, there are a few workarounds and potential fixes, but the company admits none is 100% certain to resolve the issues.

The most likely necessary thing to do is update iTunes, Apple says, or at least follow the steps in iPhone, iPad, iPod touch: Troubleshooting USB connection.

The ever-successful resolution - Test the device with a different computer - is also listed.

“If the same issue occurs on more than one computer, restore the device setting up as new, following the steps in this article,” Apple says.

In case their device does sync well with a different PC, users are advised to check with their computer manufacturer for any available updates to the USB chipset.

Cupertino explains that anything from driver updates to BIOS updates can work to fix the issues, but it is also known that certain Intel chipsets may need a firmware update to fix these kinds of problems.

“Test connecting your iOS device to an external powered USB 2.0 hub, and then connect the hub to your computer. If your device syncs successfully, but your computer's built-in USB ports still have the issue, consult your computer manufacturer for updates to your computer's built-in USB chipset,” reads Apple’s detailed step #5.

Finally, failed syncing could also be the result of antivirus or firewall software working to prevent external access to the contents of the PC’s hard drive.

A guide titled ‘iTunes for Windows: Troubleshooting security software issues’ is available for those who believe it’s the security of their PC that’s preventing the iDevice from syncing properly.
