What CmisSync is

CmisSync keeps work documents, folders, and metadata synchronized between a CMIS-compliant enterprise content-management server and a local computer. Users choose specific folders, including folders from multiple repositories, and can read or edit synchronized files offline; changes transfer when a network connection returns. The software uses the connected company file server or private cloud’s accounts and permissions. CmisSync is free and open source, with a separate Business add-in. The free plan supports CMIS-compliant servers and unlimited document size and quantity, but excludes professional support, single sign-on, Windows Explorer integration, and zero-configuration setup. Business adds those capabilities, document locking, and Windows tools for document history and offline metadata editing. Listed tested servers include Alfresco, EMC Documentum, SharePoint Server, NemakiWare, and Nuxeo; Office 365 is excluded from that SharePoint listing. Downloads are offered for Windows, Mac OS X, and Linux, with Mac OS X and Linux identified as beta. The 100-user Business pack costs $6,000 a year.
