I sometimes buy rice noodles from an Asian grocery, especially since certain sizes (like sheets) are hard to find in dried form, and the finished texture is different.

I've tried soaking them both in warm water and in cold water to help separate them, but inevitably end up with a bunch of torn noodle bits instead of the nice spongy rice noodles I wanted. Given that selling week-old fresh rice noodles is common across Asian groceries, there must be some way to separate them. What is it?
Update: I'm talking about noodles like this:
