I'm having issues extracting any data. The extracted text file is empty (0 kb). I've followed your instruction and the video instruction posted on page 5. I've tried 4 methods...

Method 1:
Original listfile.txt placed in the same folder as RMPQEx.exe, as well as the map.
(Opened map.w3x)
(Used original listfile.txt that came with the download)
(wc3 path: D:\Battle.net\Warcraft III)
(Ticked) Ability data & Item data
(Extracted to same folder)


Method 2:
used current listfile.txt (1.21.21) placed in the same folder as RMPQEx.exe, as well as the map.
(Opened map.w3x)
(Used listfile.txt 1.21.21) - only 1 listfile.txt in folder
(wc3 path: D:\Battle.net\Warcraft III)
(Ticked) Ability data & Item data
(Extracted to same folder)

Method 3:
Same as method 1, but used a different wc3 path
C:\Users\User-name\Documents\Warcraft III

Method 4:
Same as method 2, but used a different wc3 path
C:\Users\User-name\Documents\Warcraft III

Thanks

Download w3x2Lni. Convert the map to .slk and then try it. That's how I made it work.

This worked for one of the maps thank you!
How do I resolve the "Didn't find '(listfile)'" error? I've inserted JJCP and Fukki in the map and the current listfile in the map already.

Have you tried just rebuilding map with w3t,w3a or w3u files depending on what rawcode list you want and then using RMPQEx?
w3x2lni is usually never necessary for just rawcodes, the above should do the trick despite map being optimized.
