You can use :

This reads the windows environment variable.

Hope this helps, Luke.

I would like to copy a folder

c:\data

into C:\Users\Matthew\AppData\Local\Temp as is.

So then the path would be

C:\Users\Matthew\AppData\Local\Temp\data

Here is what I have so far

<pre><code>public void copyToTemp(File source){
 try {
 File dest = File.createTempFile(source.getName(), null);
 FileUtils.copyDirectory(source, dest);

 //change the source folder to the temp folder
 SOURCE_FOLDER = dest.getAbsolutePath();
 } catch (IOException e) {
 e.printStackTrace();
 }
}
</code></pre>

How do I copy a folder into the temp directory?
