VMWare shared folder out of sync

After booting the guest system, the shared folders are in sync and all works well. As soon as I make a change to one of the files on my host system (Windows 7), the file on the guest system (Ubuntu) loses its last characters and still has the old version. The actual change is not synced. However, the version on the guest gets truncated. If I delete the file on the host and create a new one with new content, everything is in sync again.

It all started happening when I updated VMWare player 6.0.1. And its happening for my Ubuntu guests only (Redhat works fine).

How can I tell VMware tools to force a sync on the shared folders?

Host: Windows 7
Guest: Ubuntu 12.04.3 LTS
VMWare: 6.0.1 build-1379776
VMWare-Tools: VMwareTools-9.6.1-1378637.tar.gz

I had the same problem. I downngraded my version to 6.0 (6.1 might work) but read this thread: https://communities.vmware.com/message/2313778#2313778

scroll down to the official answer.

The simplest maybe to downgrade back to 6.0.1 tools for now until this gets addressed in the next release of tools. Or as another user stated earlier in the thread, disable the sharing and enable the sharing feature (or manually from a terminal shell) remove and recreate the shared folder mount under /mnt/hgfs.
