1. Choose your folders
Add every folder with movies or shows you want prepped — one drive, several drives, whatever you've got. Covers get saved onto every folder you add here.
2. Optional: lock it
If you're the one who owns this drive, set a password now — once it's brought aboard, this decides who else's phone/computer can pick more folders to share from it. Everyone can still watch whatever's already shared, password or not. Leave blank to skip. For this to cover the whole drive rather than just one folder, choose the drive's top-level folder above (not a subfolder like "Movies").
3. Fetch & save
This can take a few minutes for a big library — it's fetching one title at a time so it doesn't get rate-limited.
