Hi Gary,
there's no "risk" as such, however by not useing some sort of source code control or configuration management, you are making a definite commitment that you will not roll back to a previous version, and you'll be doing your own backups, and making sure that if several people require access to a particular file at the same time, that only one person is going to be allowed (by agreeing to it) to modify the file.
There's nothing that says you have to go through the TestStand sequence editor and the other workspace and projects to do the source code control.
If you prefer, then use Visual Source Safe as a stand alone interface, and check out the files by hand to your local drive, and then work on them, and then check them back in once you're finished.
Of course, you have to make sure that your relative and absolute paths are correct when you do check out the files.
By going through the TestStand sequence editor to check in and check out files, it's more convenient for most people, since they don't have to dive around two environments (TestStand and VSS) to get to the point of being able to modify a file, or even find out if someone else is modifying it.
Hope that helps.
Thanks
