Well, I almost had a great idea that might have helped you quickly... but as usual, eq.mapfiend.net is down. Or at least unavailable from where I am. The maps themselves use the short-name. I linked my 7/2005 version of
allmaps_soe.zip here, but as you can tell by the date, it'll be missing DoDH+ maps I am sure. Just the map names are in
this file
Another site I used to use that is apparently no longer maintained is eqmaps.com. Check this link, might have something you need.
http://www.eqmaps.com/locsheet.php3 - I am certain this is way out of date, too.
Whe I did a dir /on *.s3d, I got about 300 files that I doubt will help you. They are still short names with no references to long names.
Here's the list anyway. Note that not all gfx files are zones. Some appear to be game objects in general.
