I am trying to create custom textures for clothing for Genesis 8 figures, but I cannot seem to find the texture files for the clothing. Specifically the OTS Swimsuit is the one I want to modify. Is there a way to do this? All I see is a .duf file where I believe the texture should be located. I am brand new to DS Pro and I am not sure where all the files are kept. Any suggestions?
Thanks.

I tried looking for the item you are referring to here at the marketplace with no luck. (Please do not provide a link if it is offsite.) Is there not a runtime/textures folder? If not the outfit may solely rely on shaders for the clothing, and a lot of clothing these days does not seem to come with UV templates, so you would need to create your own using UVMapper. (There is a free version just search in google).

Thanks. In Daz studio the content library calls it OTS Swimsuit. The actual product is H&C One Piece Training Swimsuit for Genesis 8 Female(s) which can be found at the daz store. I looked for a textures folder but all I show in the Mydazlibrary folder is a data folder that doesn't seem to contain anything relevant. Thanks again. :)

In most cases, if the content has texture files those files are usually found under the runtime folder.

According to the read me they are in /Runtime/Textures/H&C/2019 One Piece Training Swimsuit outfits for g8f texture/
