Do I have to use the default installation path?

I successfully picked my non-system NVMe SSD to install the initial stub of the game and then, as noted above, successfully changed the location to download the 95 Gb “update” to the same non-system drive.

For certain components such as the rolling and manual caches, even though you have them installed in actuality somewhere else, you will see file tokens in a FS folder in appdata on your system drive.
