WinFsp mount as BOTH a drive AND a folder simultaneously?

Hello! I’m struggling with Cryptomator’s mount options, as I can’t seem to mount the drive in a way to get it to work with all my software at once. I use WinFsp (Local).

  • if I mount a volume as a drive letter, it lets me use WSL and other tools directly on the Cryptomator drive. But, I can’t use backup tooks like macrium.
  • if I mount as a folder and not a drive, this inverts. I can use my backup tools, but my WSL (and some other tools) fail to recognize the files.

Thoughts? I want both - I wonder if we can mount as both simultaneously, for example…

Hi. This is not possible.

As @Michael already wrote, Cryptomator cannot do that. But it is possible with Windows tools:

subst! I think the last time I used that was to spoof mounting CDs on my old Dos machine.

Thanks for the tips. After some fiddling, it seems to work really well

  • if I run subst as administrator, it doesn’t reflect my local user, run subst as a local user
  • subst isn’t persistent so needs to be re-run on boot. People looking for a permanent solution should put a startup script.

This works really well. Both the folder AND the subst mapped drive works with my backup software and everything else, where mounting as a drive directly doesn’t. Further, some programs can’t see the mapped folder (e.g., pycharm), but can see the subst drive. Great!

Hi, any chance to get more information how you managed it?
When i did: “subst z: \path\to\winfsp-folder” i can see the new drive in Explorer
but it is not mounted in WSL2 (/mnt/)

Would be nice if you can give me a tip. thx

I never got it to work robustly with WSL, and having to re-do it on each boot caused all kinds of issues… even with making a script, it depended on timing, etc. So I gave up.

This mount issue with Cryptomator - where I have to choose between access to my backup software vs. WSL, is the primary pinch point remaining from switching away from Boxcryptor.
