Stop taking over .mat files. *I didn't even instal Access*
.mat files are used by many apps, two of which I use almost daily - Unity3D and VRay in 3ds Max. Somehow they get along. Maybe because they don't try some bargie file extension takeover tactic. Wasn't there a time when this was in poor taste? OK .mov I get it, very rarely is anything else going to use that file extension. Go ahead, Quicktime. But Microsoft - .mat? Seriously? And not just the "open with", but the nature of the file(now a shortcut)?
Some time in the last 24 hours, I'm guessing, Office and/or Windows applied some sort of update. Bam, changed all .mat files to shortcuts. Zero notification or opportunity to say "no, do not takeover .mat files by Access". In fact, why even, when I DO NOT EVEN HAVE ACCESS INSTALED.
This may be a bit verbose because dozens of .mat files from FBX exports have been turned into shortcuts, which unsurprisingly, breaks their relationship in Unity3D - particularly if the takeover happens while Unity is open. Which then causes an infruriating duplication and disconnection of file associations in the Unity editor if you don't notice it happened.
In 3dsMax/Vray material libraries. Even re-associating the files left them broken. They imported, but were missing about 2/3rds the materials. It's not just the simple "open with" propertiy that is changed, making it a shortcut screws with other stuff. We keep our vray material library files in a zipped backup so this fool process doesn't screw us up again.
