django-filer is a file management application for django. It handles uploading and organizing files and images in contrib.admin.
Custom model fields are provided for use in 3rd party apps as a replacement for the default FileField from django. Behind the scenes a ForeignKey to the File model is used.
The code is hosted on github at http://github.com/stefanfoulis/django-filer/ and is fully open source. We hope you choose to help us on the project! More about how to contribute can be found on the wiki.
