Remarks

This type of dialog box presents the user with a list of file names. It allows the user to select a name from the list (or type the name of an existing file), and provides the ability to specify drive and/or directory if necessary. If a user enters a file name that does not already exist, Windows displays a modal dialog box indicating that the file name does not exist for the specified drive, directory, and file type.
