Was recently working on a custom.xml for a client with USMT 4.0 and was struggling with getting my exclusions to work. My syntax appeared to be correct, however it wasn’t excluding the music file extensions I had created like it was supposed to. It was excluding them on the drive, but not on the desktop where I had placed some files to test.
After some searching, I came across this great blog post:
After reading through that post, I realized I had the incorrect syntax in my custom.xml. My context was set to context=”System” instead of context=”UserAndSystem”, doh! After making that change and testing, I finally got the behavior I was expecting. Mind the details!
So be sure to read the above link for the following issues.
