Two nextcloud folders in Internet Explorer in Windows 7

I have installed the nextcloud desktop client in Windows 7 (64bit). Now I have two nextcloud folders (named Nextcloud and Nexcloud2) in my Internet Explorer (and in the Windows users folder, too). How do I get rid of the second folder (named Nextcloud2)?

I have removed the folder ‘Nextcloud2’ in Internet Explorer and under ‘users’. It seems to work. So far there is no error message.
