print directory tree

Question

I have to print a directory tree (like tree command), example:

 .
 +---A
 |   +---IMAGES
 |       +---BACKUP
 +---ADOKS
 |   +---ROZDZIAL_2
 |   +---ROZDZIAL         


        

Answer 1

Think of it like this -

procedure printOutput(file, depth):
    print "|   " depth times;
    print "+---" + file name;
    print new line
    if(file is a directory):
        for(each file inside file, say innerFile):
            call printOutput(innerFile, depth + 1);

Hope that helps.
