Question

Does anyone know of a good open source client document management system?

Possibly using Joomla or WordPress?

I need to be able to allow different clients to log into the website to download their documents and upload their documents?

Any ideas?

Have you taken a look at WordPress’s Document Revisions?

WP Document Revisions is essentially three things:

1. A document management system (DMS), to track, store, and organize
   files of any format,
2. A collaboration tool to empower teams to collaboratively draft, edit, and refine documents, and
3. A file hosting solution to publish and securely deliver files to a team, to
   clients, or to the public
