Long ago I was thinking of putting a cloud service for students of FCE-UNRC.
Eventually I found a server and client program that allows me to meet the needs:
– Do not rely on services (Google Drive or DropBox)
– Share documents
– List of Contacts
– A Document Viewer
OwnCloud has many more functions.
The ownCloud Sync Client is a desktop program you install on your computer. Specify one or more directories on the local machine to sync your ownCloud server, and Always Have your latest files wherever you are. Make a change to the files on one computer, it will flow across the others using these desktop sync clients.
The website to download the program and complete documentation is: https://owncloud.org/
