I prefer to use stand-alone ($$) DSF Tools, but that is slow, really struggles with hi-poly meshes. And, sadly, the package is now unsupported following death of its author.
Plan_B is to use DS. Although its UI gives me a prompt migraine, I've put together a sorta 'strip map' for the work-flow.
Essentially, you add link to an 'external library', do the biz, then remove link. IMHO, DS makes it harder than necessary...
For example, I'll use a neat 'stone wall with front floor' DS freebie by kalhh, which I found on DA.

If you've not visited DA recently, be aware that pages may 'time out' after too-few minutes, such that [V] download button under piccy fetches HTML page, not the file you want. Just refresh page to resolve...
Download zip, shortcut and piccy to convenient folder location, eg WIP_10
Open folder, 'un-zip to current directory', gather zip, shortcut and piccy into this new folder, which has DS model's data, props, runtime sub-folders etc. Make folder.jpg to taste. I prefer 350x350, YMMV.
I'll assume is 'Prop' rather than 'Hair', 'Character' or whatever.
Open DS
x the 'Welcome' pop-up
Right click on DAZ Studio formats, left-click on 'Add Base Directory'
Browse to your new folder holding those DS sub-folders. (NOT to any DS sub-folder within.)
Select it.
Nothing much seems to happen, but DS has now 'acquired' it.
Left Click on teeny-tiny > beside DAZ Studio formats
Last in that list should be an [S] with the new folder's name.
Left click on teeny-tiny > and work down DS' Props folder tree until you reach the file, when a thumb-nail pops up in next column.
Drag / Drop thumbnail into main view-port as sanity check. Materials / textures should auto-load.
Go up and across to the DS _File options list
Left click it.
Go down to Export.
Enter file name, eg TEST1
'Save as Type', select Wavefront Object (*.OBJ)
Enter.
A busy page of OBJ export options pops up.
YMMV, I usually go with...
'To: Poser (1 Unit = 8ft)' which auto-scales to 0.410105%
Ignore 'axis conversion' and 'invert positive direction' options.
Then there are two columns.
LHS defaults seem to be...
Ignore Invisible Nodes, Use Bone Welds, Write UV coordinates.
RHS defaults seem to be...
Write Groups, 'Use Node Names', which I change to 'Use Existing Groups'
Write Surfaces
Write Material Library ( The 'MTL', I think ?)
Original maps.
Accept.
OBJ+MTL created promptly.
Note MTL may only call 'Diffuse' texture, the Kd, which DS knows as 'Albedo'. You'll need to manually load others via Poser's Material Room.
If you move OBJ+MTL, you'll have to edit call-paths with eg Wordpad.
If you want to remove DS' link, left-click teeny-weeny > beside Daz Studio Formats.
Go down to [S] with new folder's name
Right-click folder.
Left click 'Remove Base Directory', and is gone from DS.
Care: There is NO 'Are You Sure ?'
But, the model's DS files, textures, OBJ+MTL etc are still in your convenient folder...
