BXR is an open source, ruby on rails file management system. It is based off of Boxroom, an open source file management project. BXR allows you to create folders, users, and groups, and assign permissions, so you can secure different folder and files. You can also search for files and folders, either by keyword, or by file content. Organization of files is easy! Besides being able to upload files to different folders, you can also add specific tags/labels to each file.
