The file galleries section of Tiki is a very flexible download manager. You can create/edit file galleries, which are collections of files. Using the permission system, you can control who can create file galleries, upload files and download files. Statistics are recorded for each download. Rankings are defined for the top-downloaded files, most-visited file galleries, and last-uploaded files. Modules are also available to display last-changed file galleries, last-uploaded files, top-downloaded files and top-visited file galleries.
You can use file galleries to distribute free multimedia files (mp3's, avi's, etc) and software (versions, patches, releases) and to add files that users can download from Wiki pages, articles, weblog posts, etc.
