I purchased my latest laptop in July 2021. When I purchased it, I bought it so it may handle the requirements of Flight Simulator. However, with the latest release, and other things on my computer, I do not have enough room on my PC to store all of the updates.
I knew this was a big program, but did not think it going to be that big, even with the updates.
My question to this group is, may I put the Flight Simulator items on a Back up hard drive and when I want to use FS, just hook up the back-up drive to the laptop and run it from there?
As for me, I changed the location of MSFS a few times - from my internal SSD (which pretty soon was too small) to an external 2 TB SSD connected via fast (!) USB-C, and then just recently back to a newly bought 4 TB 2nd internal SSD.
Actually, you can have
MSFS itself on a certain drive of your choice (using the Windows builtin App move feature)
Your MSFS contents (the “big stuff”, >100 GB) on another drive (by changing the useropt.cfg file)
Linked folders on another drive/other drives into the “Community” folder (using 3rd party software)
This gives you a lot of flexibility in connection with your HDD space
There are some excellent tutorials out there. Just search for “move MSFS to new drive”. This is one of them.
