RAMFS is a "remote file system" (as opposed to a "local file system") meaning that it isn't associated with a hard disk partition. Instead, drive letters are created through OS/2 calls. OS/2 doesn't know the internal data format in the file system - it only accesses the data through special file system functions.

Files are stored in RAM. This means that the data are lost when the system is rebooted. It is useful for holding temporary files - just let the TMP and TEMP variables point to a RAMFS drive, and your temp directory is automatically cleaned up at each boot.

A RAMFS drive always reports a free space of 64 MB. This is an arbitrary number, and it doesn't mean that you can only store 64 MB -- RAMFS just has to answer something when OS/2 asks about the amount of free space.
