KnowledgeTree is document management system that makes it easy to secure, share, track and manage the documents and records. It is geared towards small businesses and departmental users and can be extended via web services or KnowledgeTree’s API.
Unfortunately, KnowledgeTree development has been halted by the original company and the software is not updated or maintained, so we have decided to take it off our library. If development resumes, we will be glad to add it back.
