Identify an imported file rather than a store download
This question concerns a video you are entitled to import from your own computer. It does not describe extracting protected subscription programmes or copying a rented film into another player. Begin by identifying the original local file and the media-folder location used by the Apple TV app. Two paths are more informative than two identical-looking library thumbnails.
Read the app’s file-management preference
Apple’s Windows Files settings document a Media folder location, an option to keep that folder organised, and Copy files to Media folder when adding to library. The latter copies a dragged video into the app’s media folder. If it was enabled during an import, the original file and an app-managed copy can therefore coexist. Folder organisation is a separate preference from whether copying occurs.
Compare a small authorised sample first
Suppose a household video was dragged from Downloads into the app and free space fell by roughly another file’s size. Inspect the configured Media folder and compare the sample’s paths before deleting either copy. Confirm which file the library item uses and preserve a backup of irreplaceable material. Do not assume that changing the future import preference automatically reorganises every file already imported.
Choose a consistent approach for later imports
If you want the app to maintain its own media folder, plan storage for the copy and retain source files according to your backup needs. If you choose a different arrangement, keep the referenced source location stable and verify playback after any deliberate move. Record the actual preference and folder path in private notes; those details help explain storage growth without blaming an unrelated streaming account.
Questions, answered
Does keeping the Media folder organised necessarily mean only one copy exists?
No. Apple documents folder organisation and copying imported files as separate settings.
