Thank you guys! 🙏
I de-selected 'save files on exit' in the mac app, but it only cleared 10GB.
So i used the AppCleaner to delete the files (and then emptied the trash) - and just got back 135GB!!!!!!! Wow, it feels so good to have all that space back, its been bugging me for years. And i thought it was only taking up 80GB.
But OMG 😱 pressing delete on the AppCleaner was the scariest thing i've ever done!!! I need to breathe again.
I've just logged into EN web and all my files are still there thank god. So a massive shout out to you all for your help.You are legends and i am so grateful that you took the time out to help me. You clearly know more than their customer support, because they told me it couldn't be done.
