title: create batch file based on date in file name and move files
body: <p>I have a large number of excel files with filenames that all end in a timestamp that looks like this:</p>
  
  <p>examplefile_2018_08_24_110222.xlsx</p>
  
  <p>I would like to move all of these files based on the month and year of the timestamp, but I would like the folder name to be the previous month. So for the above example, I would want to create a folder named July2018 and move that file into that folder. Is it possible to do this with a batch file?</p>
