Open FileChooserDemo. Select Windows Look and Feel and Open a FileChooser. Through the filechooser browse to a restricted location in the system.

e.g: C:/Program Files/Java/

Try creating a folder using the new folder Icon and then try to rename it. The FileCHooser Shows this as allowed.

Now using a native application FileChooser browse to the same location as above and check the folder. The Folder that was created cannot be seen there.

Conclusion: The folder is never created but the JFileChooser shows that it was created and gives a false impression.
