I am using Dropbox 244.3.6525 on macOS Tahoe 26.3. My Dropbox folder is in Users/Username/Dropbox, and this is what is set in the Dropbox sync preferences. However, it seems that an application looking for something using the path ~/Library/CloudStorage/Dropbox has created another Dropbox folder there, which is now syncing in addition to my other Dropbox folder, filling up my disk. I can't tell it to stop, as Dropbox app still considers Users/Username/Dropbox to be the Dropbox folder, so only there can I set things to "online only". Meanwhile ~/Library/CloudStorage/Dropbox is filling up and I can't stop it.
I found other references to multiple Dropbox folders on the forum, but they all seemed to have just one of them syncing. I have both syncing and can only stop one of them. What should I do?
