Pyrogenesis Object Model : VFS (Virtual File System) Interface

Scope: this documentation only covers the Javascript binding, not VFS itself.

These stateless functions provide basic file system access within the VFS sandbox. Expected use is in map/saved game selection dialogs; more complex tasks should utilize the complete vfs.h native code interface.

VFS functions
