This window is raised by Edit Working Tree Set buttons in the Navigator's Project menu or the Welcome-to-Qef window.

There are two major sections of the window:

Available Trees:

a list of tree-records that match the specified qdsrv filters

The Working Tree Set:

list of current selected trees -- known as the working-tree-set

The purpose of this window is to modify the list of project trees directly available in the Navigator.

Selected Available Trees list tree-records can be added to the Working-Set using the Add or Add All buttons.

Similarly selected Working-Set tree-records may be removed from the list using the Remove or Remove All buttons.
