title: Why is lua crashing after extracting zip files?
body: <p>I have the following code but it crashes every time it reaches the end of the function, but it successfully extracts all the files and puts them in the right location.</p>
  
  <pre><code>require "zip"
  
  function ExtractZipAndCopyFiles(zipPath, zipFilename, destinationPath)
      local zfile, err = zip.open(zipPath .. zipFilename)
  
      -- iterate through each file insize the zip file
      for file in zfile:files() do
          local currFile, err = zfile:open(file.filename)
          local currFileContents = currFile:read("*a") -- read entire contents of current file
          local hBinaryOutput = io.open(destinationPath .. file.filename, "wb")
  
          -- write current file inside zip to a file outside zip
          if(hBinaryOutput)then
              hBinaryOutput:write(currFileContents)
              hBinaryOutput:close()
          end
      end
  
      zfile:close()
  end
  -- call the function
  ExtractZipAndCopyFiles("C:\\Users\\bhannan\\Desktop\\LUA\\", "example.zip", "C:\\Users\\bhannan\\Desktop\\ZipExtractionOutput\\")
  </code></pre>
  
  <p><strong>Why does it crash every time it reaches the end?</strong></p>
