If you ever update Garmin maps, read this!

I could never understand why my laptop C drive was filling up so much! When it got down to only 10gb remaining after downloading the latest Garmin Map update to my Zumo 660 and PC I had to do something.
I always delete the old maps after an update, but still disc space was disappearing!

The problem is when you download Garmin map updates they go into a temporary folder, BUT after the update is complete these huge files are not deleted. Using the method below I recovered 60gb of disc space! What a crap system!!

The fix:
1. Press the Windows key + "R" to open the "Run" command.
2. Type in %programdata%\garmin\coreservice\downloads\map and then press "Enter".
3. Here it will list all the maps (in folders) it still has stored in temporary memory. Just have a look at the size! Right-click on a map folder you want deleted.
4. Select "Delete".
5. When prompted, confirm you want to delete the folder.
Now, the map should be in your recycle bin. If you empty it, you will gain space back on your hard drive.

Good advice. I was aware of it simply because my system disc is a quite small solid state drive and I need to keep on top of all the crap that gets put there by various software producers - particularly those who provide no option for installing to another location. They seem to be getting fewer, but Garmin are certainly one of the culprits. I’ve seen it stated that this is due to updates and some claimed need to interact with the operating system. But, as other products from other producers facilitate that on a different drive, perhaps it is reasonable to get a hint of the smell of bullshit?

Thanks Red Leader, I just got 60gb back. 6 x 10gb files. I have gained before by deleting old Windows System Restore back up files - another system resource hogging scam. They do the same thing, just keep adding without deleting or even advising the user to delete the older ones now and then. With just a bit of tidying and deleting the Garmin and Windows files I have transformed my almost full 500gb C drive to 240gb left .... :)

You can remove old out of date mapping using the Add/Remove Programs feature in the Control Panel. A bit hidden in Win10 but it's there. On my laptop, that has a smallish SSD primary drive, I install the mapping on a 2nd bigger SSD that I installed. Even so I keep this 'slim' by only having current mapping.

I Religously remove old Garmin Maps as you do, so was somewhat surprised to see I had over 60GB of old data on my hard drive by doing as Red Leader suggests.

However, I have two Garmin devices a Zumo 550 which uses NT Maps, and a BMW Nav V (which is pretty much the same as the Zumo 660) which uses NTU maps, it would appear, looking at the dates of the map folders, that it was only the NTU maps that were stored and not the ones for the 550.

I don't know whether it's relevant but I was told the only difference between NT and NTU maps is that "NTU includes certain characters/alphabets not in the NT map, U stands for Unicode. Unicode version can display cyrillic and some other languages characters and signs (like greek, polish,latvian etc)" ... so I would have thought the choice of map is more about where you're going than what device you're using?
