Several iPad users have reported getting “The iPad cannot be synced. The required file cannot be found” error message when syncing photos while everything else syncs successfully.
When transferring photos to an iPhone or iPad, the process creates a file called “iPod Photo Cache”. If the cache gets corrupted for whatever reason, the error message will be the result.
- Quit iTunes
- Open Finder, navigate to your Home -> Pictures folder
- Open Pictures folder
- Right-click the “iPhoto Library” folder and select “Show Package Contents”
- Find “iPod Photo Cache” file and drag to desktop (or delete this folder; The iPod Photo Cache rebuilds itself)
- Close Finder
- Reopen iTunes and sync. The error message should no longer appear.
