The first thing is to find the folder number for the Steam cache. You can find it by Googling the max action store page. For some reason this number doesn't show up on steam. It is the number that shows up in the address after "app/"

"app/853770"




Next go to Steam settings and turn off Cloud Synchronization




Now go to Max Action in your library, right click and go to Properties
Turn off Keep games saves in the game cloud

Now you have to find your Steam folder Program Files (x86) > Steam


Looking for the User Data folder
Click on the numbered folder



Now find the folder number from the google search "853770"



you can delete all this stuff

You should now be using less of your steam cloud storage and should be able to upload larger maps and weapons to the steam workshop!!

Before was using over 35mb of cloud storage:



After now only using 2mb:




you will see this little cloud warning but it should resync when you launch you game as long as you reactivated the cloud features first


Now MAKE SURE YOU TURN THE CLOUD SAVING IN SETTINGS BACK ON AND TURN ON THE CLOUD SAVES FOR MAX ACTION

This should be done at the users own risk! It has worked for some users but make sure to re-enable all cloud saving at the end or you will risk losing your projects!
