Quote - @MaryHines - Do you mean I should do that in Poser? I can't see the files in Win 7 explorer..

u would need to rightclick on the folder that the files or other folders are in

 

(this might also help for now : http://www.softpedia.com/get/Multimedia/Graphic/Graphic-Viewers/P3dO-Explorer.shtml

 

(especially since P3dO will let u see the Poser files & folders & let u rightclick on them to open 'properties'/Security/Advanced'/'Change Permissions'/Edit

afterwards as an added measure, I would also rightclick on the Poser folder and go to  'properties'/Security/Advanced'/'Change Permissions'/Edit
