Transferring files from PC to iPhone is not so easy as you transfer files to an Android phone. If you want to do it in Apple’s way, you could only sync files from PC to iPhone with iTunes. Because the rule of iOS, sometimes you might have problems when syncing iPhone. One of the problems is “An unknown error occurred (-54)” and then you cannot sync iPhone. This could be annoying because Apple has given its only way for you to transfer files from computer iPhone but it seems corrupt. This problem often happens on Windows 10, but Microsoft does nothing to solve it.
When issues arise, you could also have the solutions. The following content would tell you why the error 54 happens and how to fix it. Your files should always be successfully synced.
Technically, the file security would be the reason if you make sure the connection is good. Apple always keeps the files on iPhone complete and safe, so if iTunes find that some files could be incomplete or unsecure, iTunes would stop transferring data and report error. Therefore, every time you sync iPhone with iTunes, you should always keep the folder clean. Do not add unnecessary files to it.
If you are syncing media files with iTunes, iTunes error 54 might happen for the location of the files could be unclear. Your purchased content might be saved in different folder on PC. The media files you are preparing to sync could be just the shortcuts.
To consolidate media files, you should go to File > Library > Consolidate Files.
Consolidating media files could gather all the iTunes contents to one folder. You could go to Edit > Preferences > Advanced to see the location. Don’t worry about that the original files would be deleted because iTunes would just copy the files to the destination. To save the space on computer, you might need to delete some files after syncing. You could also backup iTunes library after consolidating media files.
Your iTunes should be up to date to avoid system glitches. If you downloaded iTunes from Microsoft Store, it would check update by itself every time you launch iTunes. If you downloaded iTunes from Apple Support, you need to check update by yourself.
To update iTunes, you should go to Help > Check for Updates.
If iTunes doesn’t have the permission to read the folder, your iPhone cannot be synced and error would happen. There are two ways to grand permission to iTunes.
First, you should unlock the folder or files. Find the folder or files you want to sync > right-click it > select Properties > select Compatibility > uncheck Read Only.
Then, you need to grand the administrator rights to iTunes. Right-click iTunes and select Run as administrator.
If all the contents you want to sync are the purchased content from iTunes, you could re-download them to solve syncing error 54. Make sure you have signed in your Apple ID and follow the steps:
Go to account > Purchased (or family purchased) to select and download the music and movies you have purchased.
After that, you should try sync your iPhone again.
If you want to sync the music or movies from other sources, you should reimport these files to iTunes because they might have been modified.
Go to File > Add File to Library (or Add Folder to Library) or just simply drag the folder to iTunes.
If there are just one or two songs stop you to sync iPhone, you should sync several files at a time to see whether error 54 happens. If there is no error, you should add more files and then sync iPhone with iTunes again until you sync all the files to iPhone or find the bad files.
