# Project menu

The Project menu allows you to perform actions (builds or compilations) on projects in the Workbench.

## Open Project

This command opens the currently selected project or projects. The selected projects must currently be closed for this command to be available.

## Close Project

This command closes the currently selected project or projects. The selected projects must be currently open for this command to be available. Closing a project will remove all of that project's state from memory, but the contents on disk are left untouched.

## Build All

This command performs an incremental build on all projects in the Workbench. That is, it builds (compiles) all resources in the Workbench that are affected by any resource changes since the last incremental build. This command is only available if auto-build is turned off. Auto-build is turned off via the Build Automatically menu option or via Window > Preferences > Workbench > Perform build automatically on resource modification.
