how do you get unlisted paths?

Most skins in the download section are missing paths in the read-me files or on the actually page itself.

He do i find the path if one is not given?

if you can tell what unit the skin is on, you can probably just use that unit's normal skin path. You can find that really easy by downloading the warcraft 3 viewer and pressing control-f to bring up a search and search for the unit. Just find the .blp path, and try using that as the skin path in the import editor.

You could also try PMing the author or posting the name of the skin for others to see if they can tell you

Thanks for the info.

By chance do you have a link or know of where i could go to get the viewer?

it's in the downloads section
