The File System API contains functions for creating, deleting, modifying and enumerating files and folders.

Methods

fileSystem.list

table fs.list(string folder)

Returns a table containing a list of files and folders in "folder"

fileSystem.exists

boolean fs.exists(string path)

Returns a boolean indicating whether "path" exists as either a file or folder

fileSystem.isFile

boolean fs.isFile(string path)

Returns a boolean indicating whether "path" exists as a file (i.e not a folder)

fileSystem.isDirectory

boolean fs.isDirectory(string path)

Returns a boolean indicating whether "path" exists as a folder (i.e not a file)

fileSystem.makeDirectory

boolean fs.makeDirectory(string path)

Creates the folder "path", this function is not recursive and won't create parent directories (makeDirectory("parent/child") will fail if "parent" does not exist). This function returns true on success and false on failure.

fileSystem.removeDirectory

boolean fs.removeDirectory(string path)

Removes the empty folder specified by "path". This function returns true on success and false on failure.

fileSystem.removeFile

boolean fs.removeFile(string path)

Removes the file "path". This function returns true on success and false on failure.

fileSystem.move

boolean fs.move(string path, string newPath)

Moves the file or folder specified by "path" to "newPath". This function returns true on success and false on failure.

fileSystem.copy

boolean fs.copy(string path, string newPath)

Copies the file "path" to "newPath". This function returns true on success and false on failure.

Interacting with the disk

Setting things up

To do a write or read from the disk, we must open an IO port.

(x)=io.open((path),"(W for write, R for read)")

Writing/creating files

After you have inputted the setup code, you do not have to input a directory.

(x):write((insert data here))

Reading

If you choose to read instead, you must put in the following code:

(y) = (x):read((insert char numbers here, leave blank for full file))

Closing it up

While I am not sure what this code does or if it's even required, at the end of each operation in the scripts I was studying, there was the following code before the lua end.

(x):close()
