XnViewMP https://www.xnview.com/en/xnviewmp/ will open your image and convert it to various formats that open in Gimp. What is described as 16 bit in your dtxbmp comes out as 8 bit.
No way in Gimp to export as that dxtbmp format from Gimp. There is a dds plugin that exports dds. Do a search and you will find it.
There is this https://www.gimp-forum.net/Thread-How-To...96#pid6196 Probably no good for what you want.
A bit of a search and dxtbmpxnew from http://www.mwgfx.co.uk/ converts to other formats (again 8 bit) and (says) it will convert back.
