Hello! It has been a long time, and CmisSync has gotten better!
Two-way sync between Alfresco and your desktop, delete/edit/move/etc on both sides.
In case of conflict, warns you and creates backup.
We fixed most crash causes.
You get metadata as a bonus!
Open source, download it here. CmisSync currently only supports Windows 7. Mac and Linux users are better off using the official Alfresco Desktop Sync tool. We are working on the Mac version right now 🙂
