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