Virtual root in a VHD mapped drive doesn't work #95

Open lucasorth opened 1 month ago

lucasorth commented 1 month ago

I'm trying to setting up the ProjFs environment in a VHD mapped drive that I created for this. Everything went well, I set the --virtroot to @"X:\" (my vhd drive letter), and the folders in the first level appears as well when I opened my windows explorer. But when I try to navigate to the second level of folders hierarchy, I mean, the second projected level, the Explorer thorws an error like this:

I wasn't be able to find any bug in the Managed-API, if it really exists or this is a "by design" limitation.

My solution requirements not allow me to create a sub folder and set the virtual root to it, cause the path would be changed.

Thanks for the report. I was able to reproduce the issue locally, and it is a bug in the ProjFS platform components that the Managed-API library depends on.

I've filed an internal bug for me to work on. I expect I can have the fix put into a future update for Windows. What version of Windows did you see this on?

Thanks for the quick response. I've tested in the following windows versions, both with the same error behavior: 10.0.19045 build 19045 10.0.22631 build 22631

Besides, I tried the vhd creation and attach process by diskpart utility and also via PowerShell commands.
