title: Command Prompt Unable to access jarfile error
body: <p>so my program takes two text files, InputFile.txt and OutputFile.txt, and copies the data from InputFile to OutputFile. It works perfectly fine when in Eclipse, but I need to be able to run it from Command Prompt. However, when I use the line:</p>
  
  <pre><code>java -jar Copy.jar InputFile.txt OutputFile.txt
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>Error: Unable to access jarfile Copy.jar
  </code></pre>
  
  <p>I have tried moving the entire folder from the eclipse workspace as some of the other questions claimed that worked, but it won't for me. Any help would be appreciated. </p>
  
  <p>Thanks.</p>
