    I suggest you employ Java's File and Scanner class. They are pretty easy to use for beginners.

    Show your code and any error messages or undesirable results received. There are more ways to get it wrong than to get it right, so it's important to see what you've done.

    Can you explain what the problem is for the posted code?
    If you don't understand my answer, don't ignore it, ask a question.

    The problem is that it prints: Folder not found.
    There is no error, but that is NOT the intended output.

    Seems pretty straightforward. File.exists() is returning false because the "data.txt" file or directory does not exist.

    In English, as written, this program:

    1. Accesses the file or directory "data.txt", which will be found relative the "current working directory" of the JVM process.
    2. If the file or directory exists, it attempts to treat it like a directory, fetch the list of files within this directory, and print them out to the console.

    It is branching at the first step, because the file or directory "data.txt" cannot be found relative to the JVM current working directory.

    Ask yourself what the program is intended to do, and where on the filesystem it is expected to do it.

    Hint: there are methods to prove to yourself where the current working directory for an Eclipse run program happens to be, if you don't want to use absolute pathnames.
