title: Weka tool : how to convert txt files into arff format?
body: <p>I'm having a data set composed of 100 txt files all contained in one folder " named Z "  &amp; I want to convert them into ARFF format. I'm using Weka tool.</p>
  
  <p>I have done that in 2 ways but in both ways I got an empty ARFF file.</p>
  
  <p>1st way :  through Simple CLI contained in weka by using the below : </p>
  
  <p>java weka.core.converters.TextDirectoryLoader -dir D:\Z > D:\ss.arff</p>
  
  <p>2nd way : through the GUI by trying to load the files using the same above convertor.</p>
  
  <p>==========================
  Note : the files are in text format " .txt " but they actually contain numbers not characters</p>
