It is possible that we want to resend the earlier exported photos a second time.
This is possible by starting the application from the start menu "Digital Photo Export->Export" or by double clicking on the file index.xmt in one of the folders of My documents\Picasa HTML-exports\.
The window as shown after starting the utility yourself.
Further the use is identical as when started by Picasa.
Tip: Double click on the USB drive to start a Windows Explorer on that drive.
Tip: Click below the USB drive(s) to change the caption on the button from Transfer to Exit.
Note: With each transfer when random is selected the result is different.
The program cannot be used for sending other photo files, because it uses the index.xmt generated by Picasa to control the process.
The File->Export Picture to Folder... of Picasa is available for that task (Export icon on the bottom toolbar is identical).
