The duplicate file problem in the library is specifically what I was looking at and obviously other have the same problem. It's pathetic that thread after thread has no response from JRiver. It's apparently a "Thanks for the cash....see ya!" operation.
EX Customer.
Because of the way the forum rolls, the 'problem' is hard to identify from your few words alone. It might have been easier to grasp had you included links to those threads for us to reference.
FWIW, duplicate files are usually only seen when an .m3u file is imported along with the actual audio files, so what you are looking at, is a reference to the file directly, and a reference to the file from the .m3u file.
Generally, what happens is, you report your problem, giving details as to how we might reproduce it at our end, and then if we can see it happen, we can advise why, and steps to take to fix things and avoid repitition. If your mind is set, that's fine, it's your choice and you're free to make it, if, on the other hand, you'd like to take the time to describe the problem, and the steps to recreate it, you never know, you just might find a solution. No guarantees, mind you, but if you don't try, you'll never know....
