I had the new SIFT 3.0 downloaded for a while, but I haven't been using it as much as I would like. I've been using the older 2.x version. One of the main reasons is that on the 2.x version of SIFT, there was a desktop shortcut that took me directly to a directory of the host OS. This is missing in the 3.0 version of SIFT. I fully admit, I don't know linux as well as I know Windows.
Quickly reading up on the issue, and I found that this mount to the guest OS should be found in mount_points/hgfs. I had that directory, but nothing was populated there. And, in the Virtual Machine Settings, I had the Shared Folders set to Always Enabled. Still nothing.
On a reboot, I noticed that there was an update to VMWare Player. I updated, and checked the mountpoints directory, but still nothing. One last google suggested running vmware-config-tools.pl.
Sure enough, after answering the questions, that did the trick. Now, in the mout_points/hgfs folder, I see a subfolder for "C". Bingo.
Now I have to get used to Unity and finding what I used to be able to find in SANS SIFT 2.x.
If anyone else has tips on making that transition, feel free to leave advice in the comments.
