title: Delete files older than 180 days based on file name date
body: <p>I'd like to write a batch file (that works with windows command prompt) which would delete all files which are older than 180 days in a specific folder, but based on the date written <strong>in the file name</strong> and not the modification date of the files.</p>
  
  <p>Here are how the files are named in the folder, they all follow this specific template : <strong>Backup_YYYYMMDDHHMMSS_FileName.ext</strong></p>
  
  <p>I found multiple examples on different websites but they were all refering to the modification dates of the files.</p>
  
  <p>Thanks in advance for your help.</p>
