Yes, it is the same
In some regional Windows versions some system folders could have different name, and at last it depends on user name
So, using system variable APPDATA path is:
%APPDATA%\Garmin\MapSource\TileCache\
and command for deleting would be:
del /Q "%APPDATA%\Garmin\MapSource\TileCache\*.tile"
for all Windows versions (XP, Vista, 7), localizations or user names
