Does B&R have any recommendations or anyone in the community have any experience with using the Windows 11 Dev Drives ( Set up a Dev Drive on Windows 11 | Microsoft Learn ) and ReFS in regards to Automation Studio or its Project files? Noted Benefits or issues?
Hi @Matt_Buck, I’m not sure if anyone has experience with this combination. But you can try getting in contact with the support team at your local office, and they will ask the R&D team. If you find or experience anything interesting, I would be happy if you shared it here with us 
@Matt_Buck Have you had any experience with AS and Dev Drives in the meantime?
We recently started storing our AS projects on a DevDrive.
In AS 4.12.8 we now see the effect that during compilation, the .typ- and .var-files suddenly expand in the Logical View.
