The files are modest sizes, there's just so many. The RAR is ~90 MB but, by time is un-packed, the VTF and MDL converted to JPG and FBX, a few PZ3 scenes saved, you're talking ~700 MB.
Yes, I could probably delete the VTF and MDL files, saving ~250 MB, but I keep learning new things about these file formats, going back to try different options...
Noesis can do them one-by one, just select each file in turn, select export option. This is handy for export of static props to OBJ. No MTL so, as for FBX, apply textures manually after import to
Poser...
FWIW, if using Noesis in batch format, you'll need
two passes, one for VTF, the other for MDL. For each, I recommend you change output path from the default to shorter...
$inpath$\$inname$.$outext$
...and remember to tick 'recursive'.
Then you can drag all the ported files up to a common folder, save digging around among the originals...
