FenrirFS is a file management application that lets you easily manage, preview, and synchronize all of your files using labels.
This software is full of original functions, such as being able to preview files without opening them, and being able synchronize folders automatically. It is possible to preview not just images, but also PDF, text, music files etc. in a separate window, to organize and add labels to multiple files at once by dragging and dropping selected files into labels. You also can automatically view the current status of files in FenrirFS using the auto sync function. It is not longer necessary to add files manually. Folders are also automatically labeled, reducing the burden to keep things in order.
