Filesystem ingest
Start with the folders you already have.
Add the folders where your music already lives. Tape reads them in place and brings the tracks into one catalog, even when the collection is spread across a working SSD, an older archive and a mounted drive.
Choose a music folder in Desktop and let the scan finish. You can then browse by artist and release, search the catalog or use the folder view when the existing directory structure is more useful than the tags.
Add another root when you want to include more of the collection. Rescan additions and changes as needed; the original files and folder hierarchy stay in place.
The source storage needs to be available for playback. If you move files yourself, check their paths in Tape and in any other application that uses them.
