movemetafs is a searchable filesystem metadata
store for Linux that lets users tag local files
(including image, video, audio, and text files) by
simply moving the files to a special folder using
any file manager. It also lets users find files by
tags using a boolean search query. The original
files (and their names) are kept intact.
movemetafs doesn't have its own user interface,
but it is usable with any file manager.
