DirectXTex has supported reading this legacy DX9 format since October 2015, as has the DDSTextureLoader.

What software are you using that you are reporting a problem with?

As long as the UNKNOWN column exists, I can't pack a new texture using the data from this dds...
dds is obtained from sacred 2 gold.

I use your texconv ​​for analysis.

I don't know what it is you are running for this output that results in 'UNKNOWN'.

Thank you. The problem has been fixed; after all, own GUI using your utility as an engine.
