Kotlin Tutorial – Learn to traverse or iterate through all files in a directory using Kotlin. We shall present you a Kotlin Example program to demonstrate on the same.

We shall use the extension functions  of java.io.File : walk(), walkBottomUp, walkTopDown()  to generate kotlin.io.FileTreeWalk on which we use iterator to traverse the directory and its contents. The functionality of the three functions is almost same except the order in which they iterate through contents.
