----------------------------------

Can you download and build trunk to see if that still happens? We hope to release 2.1 soon.

> Using copyFrom when you don't have access to create the parent folder fails even when the parent folder exists.
> I have the folder structure of:
> /home/usera/subfolder
> Userb has r/w access to the subfolder and read access to the parent folders.  CopyFrom with a destination of "/home/usera/subfolder/file" fails 
> {code:borderStyle=solid}
> Caused by: org.apache.commons.vfs2.FileSystemException: Could not create folder "file:///home/usera/subfolder".

> It looks like the issue is that the code doesn't check if the destination folder exists before calling create.  Create throws an exception any time the folder is not created (even if it didn't have to create the folder.)
