title: Loading data from text file from only a part of the file name
body: <p>I have a lot of data in different text files. Each file name contains a word that is chosen by me, but they also include a lot of "gibberish". So for example I have a text file called <code>datapoints-(my chosen name)-12iu8w9e8v09wr-140-ad92-dw9</code></p>
  
  <p>So the <code>datapoints</code> string is in all text files, the <code>(my chosen name)</code> is what I define and know how to extract in my code, but the last bit is random. And I don't want to go and delete that part in every text file I have, that would be a bit time consuming. </p>
  
  <p>I just want to load these text files, but I'm unsure of how to target each file without using the "gibberish" in the end. I just want to say something like: "load file that includes (my chosen name)" and then not worry about the rest.</p>
