Clicking the forge jar on my server file doesn't create the mod folder

[Hyyugo]

i'm trying to make a modded 1.12.2 server, installed the forge client, then installed it into the server. but when i click on "forge-1.12.2-14.23.5.2859" to create the mods folder, no folders are created and nothing happens.
