Supertag is a tag-based filesystem, written in Rust, for Linux and MacOS. It provides a tag-based view of your files by removing the hierarchy constraints typically imposed on files and folders. In other words, it allows you to think about your files not as objects stored in folders, but as objects that can be filtered by folders.
