And SystemDialogInput[] does return the file, not open it. "FileOpen" refers to the style of the file-picking dialog. Open-style dialogs have different properties than Save-style dialogs. Open-style dialogs allow you to pick more than one file and require you to choose existing files. Save-style dialogs warn you if you've targeted an existing file (which would potentially be overwritten). And there's some different labeling, too. As I believe somebody else already mentioned, FileNameSetter[] does this, too. The difference between SystemDialogInput and FileNameSetter is that FileNameSetter is intended to be used in a Dynamic interface for keeping a Dynamic variable up to date (you can think of it as equivalent to the '...' button you sometimes see next to an input field for setting filenames in some dialog boxes), while SystemDialogInput requests the filename immediately and stops execution of your input until the name is returned. SystemDialogInput is more appropriate for any procedural bit of code. Sincerely, John Fultz jfultz at wolfram.com User Interface Group Wolfram Research, Inc.
