Command button to open folder

I'm working on an accident tracking database. Users input accident details
on a form, which automatically assigns a case number based upon date & time.
They also create a folder on the computer to store pictures of the accident
scene, and name the folder with the case number. Is it possible to have a
command button on this form that would create a new folder and name it with
the case number?
Later, when a committee reviews the accidents, an overview is displayed on
another form. Is it possible to place a command button on this form to open
the folder with the same case number to view the pictures?
Any help to simplify the input process would be appreciated.
