Filr is a simple tool for modifying three important file properties - filename, tags, and comments - all within a simple, unified interface.
Filr steps through each file separately, so you can apply different tags and comments to each one. A large preview shows the file currently being modified.
Filr supports OpenMeta, an open standard for metadata storage. It's instantly compatible with many 3rd-party applications, including those from Ironic Software, creators of OpenMeta.
Filr is not intended to replace those applications; rather it is designed to supplement them by allowing for tagging individual files in a lightweight, frictionless package perfect for integration in your workflow.
