Moving installed Garmin Map from C: drive to another drive/partition

I partition my HDD and try yo have as few programs or large files on my Operating Drive C:{ to make the computer a little faster rather than having to search through useless stuff. Since Garmins Maps take up well over 4.4 GB for the full NA map I like to have it on my second partition or secondary HDD. This could also be useful if your C: drive is getting full.
Here are instructions to move it from your C: drive to your secondary drive maybe the D: drive. By doing it this way BaseCamp and MapSource will find the location.
The maps are probably in C:[ProgramData]Garmin. You'll want to make the same folder on the D: drive.
YOUR FILES MAY BE LOCATED ELSEWHERE!!! I found on one of my computers the ProgramData folder was hidden. I had to unhide it using Windows Explorer.
Instructions, INCLUDE the % marks !
Moving Installed Garmin Maps to another Location on a Windows Computer
Installing maps to the computer will allow them to be viewed in BaseCamp and other applications. In some circumstances, it is beneficial to relocate the map data to save space on the system drive.
To move the map files to an alternate location:
Windows:
Press the Windows key + R
Type %programdata% and press Enter
Open the Garmin folder
Open the Maps folder
Right-click the desired map to move
Click Cut
Browse to the desired alternate location
Right-click a blank area in the directory
Click Paste
Browse back to the Maps folder on the C: drive (%programdata%GarminMaps)
Right-click a blank area in the directory
Select New
Select Shortcut
Click Browse and browse to the location of the relocated map
Click Next
Click Finish
Start BaseCamp or MapSource to view the maps. The maps will be loaded from the alternate location.
The maps in CoreServiceDownloads, they can be safely deleted, the files are downloaded initially to create the files etc that BaseCamp and your device uses, once that's done you can remove them.
This may save more HDD space.
Wouldn't it be
Wouldn't it be simpler/quicker/more efficient to just make a symbolic link from the original folder to where-ever you put them.
Either include the full path in source or change to the folder itself before executing.
mklink /d "source" "destination"
example: map folder cache to
mklink /d "cache" "s:/temp/chrome/cache"
My drive S is a ramdisk where all the browser garbage is mapped to.
Note, the forward slashes should be backslashes... Forum doesn't like back slashes.

Download JaVaWa's GMTK program, it will do all this for you with a few clicks.

Thx
Thanks sussamb, but I prefer to not have to install a program for such a simple thing which has worked for me several times flawlessly.

Fair enough
It was aimed more at those who want to do it but not necessarily follow all your steps. GMTK is a great utility for anyone with a Garmin device, and does much more than simply move maps. JaVaWa's device manager is another. I've used them for years and wouldn't be without them

Never heard of these. I will definately research this. Thx.

New Map Updates Can Be Installed In Another Partition
Ran into exactly this issue and Garmin Tech support no help at all. HOWEVER, they did point out that Garmin Express [when installing a map UPDATE, not a re-install] will offer you the option to install that map in a location OTHER THAN the c:partition departition default location. That said, YOUR approach worked like a charfault location. That said, YOUR approach worked like a charm for me when the issue is moving it from the c:partition and having it available within BaseCamp.

What Garmin failed to point out is that it doesn't work. When I try to take that option the only location it allows me to select is my desktop. I have to manually move the map and set up a shortcut so I can have my maps on D (1TB SSD) instead of the 256GB NVME drive where Windows is housed.

The GMTK program I mentioned above will do this for you, for those not so computer literate.
