If the given directory contains both files and directories then the files
will be ignored and only lowest level of subdirectories will be considered.
Example:
If the input directory has following structure.
/input/directory/\<files>
/input/directory/\<directories>
And if the data that to be considered is available in files in
"/input/directory/" then it will be ignored.
