I received a warning that my C: drive is full and had to do some tidying up. One thing which surprised me was the presence of old versions of maps; about 18GB's worth.
I found them here, C:\ProgramData\Garmin\CoreService\Downloads\Map deleted the old ones and kept the latest with no apparent issues.
