Library

The library is how TagStudio represents your chosen directory, with every file inside being represented by a file entry. You can have as many or few libraries as you wish, since each libraries' data is stored within a .TagStudio folder at its root. From there the library save file itself is stored as ts_library.sqlite, with TagStudio versions 9.4 and below using a the legacy ts_library.json format.

Note that this means tags you create only exist per-library.
