As I installed several maps from Freizeitkarte I'm now running out of space on my Fenix 7 and was checking which maps I could delete.
I found these descriptions of the Epix 2 that helped me identify most files sort of:
gmapbmap.img: - Worldwide base map
gmaptz.img - Timezone map
D1399430A.img : Golf Map - CourseView Europe, Middle East & Africa
D2419380A.img : Golf Map - CourseView Pacific
D2471430A.img : Golf Map - CourseView Americas
D4713070A.img : DEM Map EU 2020.10
D6184110A.img : TopoActive Europe 2021 20. East v21.20
D6185110A.img : TopoActive Europe 2021 20. West v21.20
D9486000A.img :TopoActive Europe 2021 20. Central v21.20
Looking at the first characters of the files in this list, I think that D9488000A is a newer version of the TopoActive Europe Central map, but that one is not shown as installed in Garmin Express.
Can anybody confirm and can I delete it using file explorer?
