Webtmpfs - a virtual memory filesystem DESCRIPTION The tmpfs facility allows the creation of filesystems whose contents reside in virtual memory. Since the files on such filesystems typically reside in RAM, file access is extremely fast. tmpfs (short for Temporary File System) is a temporary file storage paradigm implemented in many Unix-like operating systems.
