cfzip - issues with zipping all files in a directory

Question

I have to save multiple files in a directory and once thats done, zip them up and make it available for download.

I have my files saved in a directory and I am trying to use cfzip to zip them all in a zip directory, however, I am getting error. Here is my code:

  <cfset sFilePath = 'D:\temp\zip\test.zip'>
  <cfset sSourcePath = 'D:\temp\data\'>

  <CFZIP ACTION="zip" FILE="#sFilePath#" SOURCE="#sSourcePath#">

It gives me java.io.FileNotFoundException: ensure file is valid zip file (access denied) error. Do we need to set up special permissions or its my code?
