I recently received Total REX.
Wow, that is some collection.
They did a great job on that, Very RMX friendly, the right amount of files per folder.
The only issue I had is most of the collections went outside the converted rex files folder into the User Libraries folder except for a few on the second DVD went into the converted rex file folder.
When I moved the folders out of the converted rex files folder into the User Libraries folder the collection names were there in RMX but if you selected them they wouldn't work.
I put them back into the converted rex files folder and they work OK.
So I left them in the locations that worked.
I am a little baffled why some collections work inside the converted rex files folder while others don't.
