Legacy format with *.img map tiles are normally stored under "C:\Garmin\.". Some 3rd part map providers store maps in their own directory structure like TrakMaps.
New GMAP format are stored under "%PROGRAMDATA%\GARMIN\Maps\." (prefered for ALL users) or "%APPDATA%\GARMIN\Maps\." (for single user). There can also be a Windows LNK-shortcut in either of those pointing to some other path. GMAP format is the new format that Garmin uses for both Windows and Mac.
It's possible to create a GMAP version from legacy IMG with Gamin MapConverter for Windows.
