Cant upload to Workshop

I want to upload my server content to workshop (Its somethong like 500mb but Im made a parts for it 5 or 4 parts of the content)
Anyway when im trying to use this command its alway saying

I tried with the windows CMD and its do the same problem I have no idea what to do
I tried with gmpu 2.2 and its alway saying error status 1 (u can see here
I tried with gmad gui too and its even not working when I click on build its not doing any thing

Your cd command isn’t being run. Just run this in CMD instead:

"D:\Program Files (x86)\Steam\SteamApps\common\GarrysMod\bin\gmad.exe" create -folder "D:\addonpart2" -out "D:\hey\part2.gma"
