Use cloud storage for archives
Cloud folders work well for storing many file types, sharing documents, and keeping long-term archives where playback workflow is secondary.
Compare
Private podcast feed vs cloud storage.
Cloud storage keeps files. Private podcast feeds keep listening workflows moving.
Use private feeds for listening
Private podcast feeds work better for recurring audio review, commutes, research listening, offline playback, and podcast-app habits.
Where Castline fits
Castline turns audio files, direct audio URLs, text, and articles into private podcast feeds instead of leaving them scattered across folders and tabs.
