Forgot to specify folder for Selective Sync. Am I now locked in to downloading entire Dropbox?

I forgot to specify my folder when setting up Selective Sync, and all folders are selected by default. Dropbox is now downloading tens of thousands of files from my team's account onto my Windows PC.

 

Deleting the files locally will delete them from dropbox.

If I pause the sync and change the settings to specify the folder I want, it does not cancel/remove the pending files.

Exiting the dropbox app or restarting my comptuer does not cancel/remove the pending files.

Relocating the syncing folder, changing the options, doing anything to get it to try to restart the syncing does not cancel/remove the pending files.

 

Is there any way in Windows 10 to

1. Stop the download in progress (I currently have syncing paused. I want to CANCEL these downloads, so that they will not resume when I resume syncing)

2. Delete the local files without deleting them in dropbox, or causing issues when syncing is resumed

3. Correctly specify the folder I wish to sync

4. Resume syncing as normal

 

Thanks in advance!
