I was setting up to continue development on a webVR application I've been developing for a while.  This is a new system, with a new setup from the prior one (had to reinstall and had changed how space is partitioned).
I have a SSD as my system drive (c:/).  I have a secondary 4TB HDD which I partitioned into 1TB sections and mounted in various places.  
1) c:/games
2) c:/users/Youzer
3) c:/users/youzer/Documents
4) f:/  (other scratch space)

I had installed the latest chromium build from https://webvr.info/developers/get-chrome/ (which is down now) https://chromium.googlesource.com/experimental/chromium/src/+/refs/wip/bajones/webvr_1_1
Which was a standalone zip so I could install it anywhere...
I tried setting --user-data-dir=c:\temp to put the data outside of the mounted partition; because I earlier ran into issues installing extensions .... 
https://bugs.chromium.org/p/chromium/issues/detail?id=117106  
but just setting the data directory did not help; and I had to move the 'installed' version to a root drive.

I was looking for a zip install for canary chrome or chromium to test with a more official build; but could only find a auto installer.  I would have to mount a partition as c:/program Files (x86) to demonstrate the problem to be caused with that (which I'm not beyond doing).
