File Close All Images
This command asks for confirmation and then closes all the images in the image tree.
A dialog box is displayed to let you choose whether or not to save the current workspace before closing all images and if so, what name to save the workspace under.
Selecting Cancel aborts the command without closing any images.
Selecting OK performs the operation currently selected by the radio buttons:
Don't Save -- close all images without saving the current workspace.
Save with name based on date and time -- saves the current workspace with a unique filename based on the current date and time and then closes all images.
Save with current workspace name -- saves the current workspace with under its name. This option is omitted if there is no current workspace name and then closes all images.
Ask for workspace to save -- lets you choose a name to save the current workspace under, saves the workspace under that name, and then closes all images.
