Flex Studio 3 integrates with CVS out of the box.  But there are people who are using Visual SourceSafe, or VSS.  Here is how to enable the VSS support in in Flex Studio 3.  Screenshots link is in the first comment.

1. Flex Studio 3, go to Help > Software Updates > Find and Install…
2. In the “Feature Updates” dialog, select the “Search for new features to install”, click next.
3. In the “Update sites to visit”, check only “The Eclipse Project Updates”, click finish.
4. You may/may not encounter dialogs for selecting mirrors.
5. In the “Search Results”, expand the “Eclipse 3.3.2″ tree, and check the “Eclipse Java Development Tools 3.3.2 …”, click next.
6. Do what is necessary to complete the plugin installation, including dealing with a Digital Signature type dialog box.
7. This requires a restart of the IDE.
8. Download the Eclipse VSS plugin.

9. Extract the zip file.  Copy the folder “org.vssplugin_1.6.2″ which contains files like plugin.xml to the plugins folder of Flex Studio, which in my case is “C:\Program Files\Adobe\Flex Builder 3\plugins”.
10. If Flex Studio is running, exit.
11. Start Flex Studio
12. Now when you go to Team > Share, you will see “VSS Configuration Wizard”.

Enjoy!
