The function 
prompt-for-files
 presents the user with a dialog box similarly to prompt-for-file, but in which multiple filenames can be selected.
The arguments are as for prompt-for-file, except that filters defaults to:
("MS Word files" "*.doc"
"HTML files" "*.htm;*.html"
"Plain Text files" "*.txt;*.text"
"All files" "*.*")
filenames
 is a list of filenames, or 
nil
 if the user cancels the dialog. 
successp
 is a flag which is 
nil
 if the dialog was cancelled, and 
t
 otherwise. 
filter-name is the name of the filter that was selected in the dialog.
If 
continuation
 is non-nil, then it must be a function with a lambda list that accepts three arguments. The 
continuation
 function is called with the values that would normally be returned by 
prompt-for-files
. On Cocoa, passing 
continuation
 causes the dialog to be made as a window-modal sheet and 
prompt-for-files
 returns immediately, leaving the dialog on the screen. The with-dialog-results macro provides a convenient way to create a 
continuation
 function.
Note: 
prompt-for-files
 is currently implemented only in LispWorks for Windows and Cocoa.
