Are there any ways or tools to dump the memory cache and buffer?

I want to check out what files are loaded in buffer. Just so it's clear, the buffers & cache I'm referring to are what show up when you run the free -m command: $ free -m total used free shared buffers cached Mem: 7800 7671 128 0 291 724 -/+ buffers/cache: 6655 1144 Swap: 5823 613 5210
