Grid paper.png  Example
Displays a list of all files and folders in the root directory of a computer as a table
Code
abc = fs.list("")
     i = 1
     while i ~= nil do
     print(abc[i])
     i = i+1
     end
Output A list of all files and folders in the root directory as a table


abc = fs.list("") <- will get all the files and directories in the system root into a table, all saved as 'abc'. i = 1 <- sets i equal to one. while i ~= nil do <- While i isn't nil, continue to do this. print(abc[i]) <- print the files and directories. i = i+1 <- add 1 to i each run so a different file/directory gets listed next. end <- end the loop.
