where is "tmpfs", with /dev/shm ?

Novell Linux Desktop 9 System Monitor shows a device named tmpfs in the directory /dev/shm. Under type it says tmpfs 125 MB with 8 K used.

I'm assuming this is a temporary file system. How can I access this "device" ? How can I see what's in it ? Should I be concerned about it's size at some point in the future ? Can it be emptied without causing harm ?

This just showed up about 2 days ago after I had burnt a couple CD's. At least I don't recall seeing it before then. It does not show as a device when I look at the partitions.

Tmpfs (aka /dev/shm) is the POSIX shared memory system under 2.6 kernels. It grows as needed throughout the use of shared memory. Only what shows as "used" is actually being used from your system.

Many programs rely on the proper functioning of the tmpfs system, so I would avoid trying to "empty" it in any way.

Thanks for the explanation on tmpfs (aka /dev/shm), I appreciate you taking a few moments to explain what that is.

Now I know not to mess with it, I couldn't find it anyway with Navigator.
