If you use a TOpenDialog component you can set its InitialDir property
the directory you want the dialog to open in. The Options property
allows you to configure the behaviour of the dialog, e.g. whether it
should allow the user to select more than one file. You call the
dialog's Execute method to show it, and once it is up the user can
navigate around the file system at will. If the directory you specified
at design-time does not exist on the target machine the dialog will
open at a defaul location. Of course you can also set InitialDir at
runtime, e.g. to the folder the user last visited and which you
remembered in a settings file.
