I understand that 8.3 file naming should be disabled when using DFSR, especially with read-only replicas. And, in general, it's good practice for performance.
BUT, is it really necessary? I understand it could cause some the outgoing replication folder on a RO DFSR replica may occur, but is this really a problem? Aside from cosmetic and the fact that it takes up space...
I ask because it's enabled on all my servers, and I'm paraoid that if I enable it, it will cause some programs issues as we use a ton of different software packages for engineering, and some are quite old....
