File Close
This command closes the current image -- this is the same as clicking the close box in the thumbnail image in the image browser. All memory and resources associated with the image are released.
A dialog pops up asking if you want to close the current image.
If the current image is a top-level image or a splitter or side-branch, all the images below it will also be closed.
After closing the current image, if any splitters remain that have less than two branches, they are automatically removed.
If Autosave is enabled (see File Preferences), the workspace is autosaved before the close operation so you can recover any lost work you deleted by accident.
Tips
To see what images depend on the current image, go to the image browser check the color coding of the thumbnails. This identifies all the images the current image depends on and all the images that depend on the current image by coloring their captions in red or green as illustrated below. The current image caption is highlighted with a white background. In this example, the middle image is current and the one below it depends on the current image since it has a green caption, and this means it would change if you closed the current image.
