Changing storage location

I’m new to eM client. I have windows 10 set so new apps etc are stored on the D drive. I then installed eM client but notice that the storage location has defaulted to the C drive. I have copied the files there to a new folder on the D drive. However eM Client won’t let me delete the existing storage address and type in the new one. 

If you want to change the database location, close eM Client and move the C:\Users_username_\AppData\Roaming\eM Client\ folder to the new location. Then  open eM Client and go to Menu > Tools > Settings > General > Storage and select the new location where you copied the eM Client folder. Lastly, restart eM Client.
