Then you have not properly explained your issue. I understood that you cannot find the folders.This page you linked is less useful to, however I also view threads about it, but nothing useful.
I want to find the directories of the maps and campaigns. The user/documents part are empty! For now I can't play custom campaigns, because the custom campaign section in the game are empty!Tell us exactly what you need and we'll try to help you.
Yes, i done that!Have you uninstalled the game before properly installing it with the installer?
Yes, but that method was not successful.Have you tried creating the folders yourself where they are supposed to be as mentioned above?
Don't move the created folder. Create the Maps and Campaigns folder within it.Instead, in my computer menu (where one can select the folders) I found a documents folder, where I saw a warcraft 3 folder. But I cannot found that folder in user/document folders. So, I put that warcraft 3 folder, which I accidentally found, in the desktop, so I can reach it from there.
Try putting the folder back. If that doesn't work, uninstall and reinstall the game.It already have the folders, the point is that I accidentally found what I want and the put the whole thing to the desktop.
