title: Convert filename in a folder from upper case to lower case (Windows Command Prompt or PowerShell)
body: <p>I have about 600 files in a folder that I need to convert form lower case to upper case.  I cannot install any apps in my machine since our IT won't allow it, hence, I either have to do it in powershell, CMD or maybe VB.</p>
  
  <p>Example file:</p>
  
  <p>dog_123.csv needs to be converted to DOG_123.csv</p>
  
  <p>Thanks in advance.</p>
