Server-based open-source installable software, creates a cloud-based repository for all of your files with functions similar to those of Dropbox/Google Drive and other similar cloud-based shared file storage solutions.
Key features include:
100% free. Open-source.
*Commercial version available (allows for further customization, without needing to share it with the open-source community)
My comment: Good alternative to the commercial cloud-storage giants, offers the possibility to anyone to create and manage its own file storage and sharing space online. All key features included. Recommended.
