GVfs (GNOME)
From Just Solve the File Format Problem
GVfs (Gnome Virtual File System) was an abstraction layer providing a virtual file system for the GNOME platform, succeeding the earlier such system, GnomeVFS, which also confusingly stands for "Gnome Virtual File System". It is unrelated to the similarly named GVFS (later renamed to Virtual File System for Git) used in Git.
