(The Explorer)

... an emulator-/emulation-agnostic, intuitive, (and even pretty close to) industry-standard file-selection dialog-box, including all the usual sorting and locating features, that your users will almost certainly be immediately be familiar with, and just as certainly feel completely comfortable with. They won't need special training, or a binder full of notes, just to point to a file to be loaded or a folder to be written to. And you know just how many places that can come in handy. Also available in a less CUBS-y, more industry-standard version.
