So I have created a new weldment profile that I wish to store in the Solidworks PGM

The system tells me the address is

Program Files \\ SOLIDWORKS Corp \\ SOLIDWORKS \\ lang \\ english \\ weldment profile

I have added file       (square tube 100x100x6.SLDLFP)

But it does not appear in the "Structural Member" drop down menu when I am doing "weldments"

And saying that the things that appear in the drop down menu dont appear in the Weldment Profile folder either

What is going wrong?
