Open a Folder in Air 2.7

Hello there,

When Air 2.0 was released, it was possibile to do something like this (c:\mydirectory\mysubdirectory has to be there obviously):

var file:File = new File("c:\\mydirectory\\mysubdirectory");

file.openWithDefaultApplication();

and the directory would be opened by using (for exampe) in windows the file explorer

In air 2.7 this code throws an error (that is a security error, in fact if I open a temp directory created with createTempDirectory it works)

"Illegal file path"

Now, please, tell me how can I harm the user by simply opening a directory on his hard disk!

How can I open a directory on his hard disk without getting this error?

Thanks in advance
