Update Star includes support for many languages such as English, German, French, Italian, Hungarian, Russian and many more.
You can choose your language settings from within the program.
If there's no need to do that you can safely delete those files as you're right, they do build up and take up a lot of space especially as files from previous updates also remain.
I'm not at all impressed in the manner in which Garmin Express leaves behind files everytime the program is used.
The same thing happened with the last map update and have no idea if it's Garmin Express leaving behind the humongous files or it has something to do with my computer ?
I do know though that in the past when using Garmin Map Updater the files were never left behind.
Anyway..I am world, a bloated tick of a human, consuming more of your resources than I have a right to, hating myself for doing it, hating myself because I can’t seem to stop doing it, hating myself because I hate myself so much.
I used Map Updater on both my 255WT using Alandb cloning method and all went extremely well without a hitch.
I don't think the average user knowns or should have to jump through hoops after doing an update to clean Garmins leftovers.
After searching the gigantic files I also did did the same for huge and large and saw that the software & voice update I did a few weeks ago for my 3597 were also on my "C Drive" !
Cheers Express installs the necessary files to your PC and then compiles your map from that.
Those files remain behind in case you want to update another device or reinstall the map onto a device.
I then used CCleaner to clean the history, cache etc.
