The icloud drive is in /users/username/icloud
I want to change that to another folder. How do I do so?
I can do that in dropbox and onedrive.
I'll assume this is about iCloudDrive for Windows (you don't mention that explicitly in your question). If that's the case, follow these steps:
C:\Users\<username>\iCloudDrive) to the new location.mklink /J "C:\Users\<username>\iCloudDrive" "<new destination>" This creates a junction (sort of a shortcut, but more powerfull) from the old location to the new location.
