TFS2010 Branching into a subfolder of another branch

Question

We have a folder structure in our source control where some things are branched, and some aren\'t.
The branched stuff follows a (standard?) pattern of Production

Answer 1

I had similar issue. I was trying to create another branch in DEV (in separate folder) from MAIN and this error popped up.

What resolved this problem for me was to create a new branch in the root and later move it to Dev.
