When I attempt to export, "Choose File" only shows a previously used folder instead of all folders on the hard drive or that have been created in LR. How do I correct this? Thankd for your help.
Have you tried using the "choose" button?
On the top of the Export Dialog select Hard Drive in the Export to: box
Under Export Location select Export to: Specific Folder
Then click the Choose... box
This should open the Explorer function where you should be able to navigate to any folder on your hard drive(s).
