# MTFS MTFS is, in effect, a standardised set of names for function endpoints implementing the [API of an OpenComputers filesystem component](https://ocdoc.cil.li/component:filesystem), over Minitel RPC. ## Function names Names for filesystem "component" functions should follow the form `fs__`, so, for example, `fs_/usr_isDirectory`. ## Functions Unless otherwise specified, functions should be inherited from, or implemented to emulate, an [OpenComputers filesystem component](https://ocdoc.cil.li/component:filesystem). More specifically: - spaceUsed - seek - makeDirectory - exists - isReadOnly - write - spaceTotal - isDirectory - rename - list - lastModified - getLabel - setLabel - remove - size - open - read - write - close ### Optional extensions #### dirstat An optional extra function, `dirstat`, may be implemented on the server side to allow clients to access directory listings with less RPC calls; it should return data in a Lua table of the following structure: ``` { [filename: string] = {isDirectory: boolean, size: boolean, lastModified: number}, ... } ```
