![]() These files are usually provided on a CD or DVD that came with your Garmin device, or can be downloaded from the Garmin website. Second, you will need to have the original installation files for the maps you want to reinstall. This includes any custom POIs (points of interest) you have created, as well as any changes you have made to the map display settings. First, when you uninstall Garmin maps, all of the customizations and settings you have made to the maps will be lost. The answer is yes, you can uninstall and reinstall Garmin maps, but there are a few things you need to keep in mind. This one's all you need to keep.If you have purchased a Garmin GPS device, you may be wondering if you can uninstall and reinstall Garmin maps. There should be another set in the folder designated by the BaseCamp and this one shoudld only be 3GB. the download folder would be holding up about 9GB if the system didn't purge it, you would see gmapprom.img on the PC. If the system didn't purge temporary files, the download folder contains the two sets of files one of them for the unit, and one set for the computer. Make sure you have invisible folders and such visible. ![]() You could also try searching for recently crated files over 500MB to hunt it down. Crawl up a few levels and see if you can find a folder beneath Garmin called downloads or similar. Look in the BaseCamp, then locate where the map is and start approaching that folder. I am not sure how the update software on Mac handles the temporary files after you're done downloading. I do use Garmin MapManager to delete the previous map versions once I'm comfortable that BaseCamp is fine with the current? Is there a link to where these unneeded files reside on a Mac? For those of us who have a laptop with a SSD, disk space is precious and if we can purge several gig that doesn't impact BaseCamp it would be very helpful. I just went through the whole twisted process yet again with 2017.20. Garmin Express should give you the option to clean them out, imo. This is why you need almost double the free OS drive disk space of a map to do an install.Įverything in Program Data\Garmin\CoreService\Downloads is only taking up valuable space after installations. To make matters worse, during an install the map build data is stored in Program Data\Garmin\CoreService\Downloads\Temp but they get deleted after install (except for the empty folders!!). As Falcon9 pointed out, Mapsource files are in Program Data\Garmin\Maps, unless you've installed them to another drive or directory (in which case there will be a shortcut to the map folder in Program Data\Garmin\Maps). I've posted about this very same issue because more OS "disk" space isn't always an option on new hybrid tablets/laptops.ĭeleting everything in the normally hidden Program Data\Garmin\CoreService\Downloads\Maps directory won't affect Map source after you've installed to your devices & Mapsource. I know some one will comment that is nothing because 3TB drives are cheap today, however 25GB is a considerable waste space on a SSD system and wasted time and space on every set of backup you make. Now, turn it back no so that you have the ability to roll back using system restore for future changes. "configure", "turn off system protection" ![]() The final step frees up the disk space, but you won't be able to roll back once it is done.Ĭontrol panel > system > system protection ![]() Make sure you're satisfied with the change. Make sure you have show hidden folders enabled in "folder options" (push alt key. To get to those folders, hit Windows+R, enter %programdata%\Garmin\ The cleanup freed up 25 GB of space on my HDD. I deleted 2016.20 entirely and kept only the installed map for 2017.10. You do not need the contents in the download folder once you've installed the map on the unit unless you're going to redeploy the map onto a different PC. The download folder for 2017.20 was using about 9GB. There's a folder for each version of map you choose to keep. I kept the other files in the folder just in case so it is 3.32GB with those in place. The latest map for North America is 2017.20 and the Product1 folder is only 2.43GB. The files used by Basecamp to use the maps on your computer are stored in %programdata%\Garmin\CoreService\Downloads Turns out Garmin installation process takes up about 13GB of space for each map. ![]()
