To save a project, choose File|Save Project (Ctrl+S).

You can create your own folders (Project|Folder, or use the context menu). In the dialog box that appears, give the folder a name and assign extensions to it. The folder and its associated extensions are added to the registry.

Clicking on a folder in the left pane gives you a List view in the right pane. Right-click for a menu. You can multi-select files in the right pane and perform the same operation on them as a group: open, compile, delete, and so on.

You can have only one project open at a time.

The BIN directory contains a utility (CAT2PRJ) that converts your Visual dBASE 5.x Catalog files to Project files.
