About cached files in "Other"
Finder and iTunes categorize cached music, videos, and photos as Other instead of actual songs, videos, or photos. Cached files are created when you stream or view content like music, videos, and photos. When you stream music or video, that content is stored as cached files on your device so you can quickly access it again.
Your device automatically removes cached files and temporary files when your device needs more space.
If storage on your device differs from what you see in Finder or iTunes
Since Finder and iTunes categorize cached files as Other, reported usage for Music or Videos might differ. To view usage on your device, go to Settings > General > [Device] Storage.
If you want to delete the cached files from your device
Your device automatically deletes cached files and temporary files when it needs more space. You don't need to delete them yourself.
