Windows browser that's enabled for multi-selection?

The Dialog class in VW Smalltalk has methods that allows a user to make a single file selection...  are there any parcels or goodies that enable a file explorer that give the user the ability to make multiple file selections?    

Dialog
                                requestFileNameWithMessage: (#openPDFfiles << #Dialogs
                                                >> 'Select PDF Files') asString
                                default: '*.PDF'
                                version: #multipleOld
                                ifFail: ['']
                                for: nil
