The Directories->Show SubDirs->Show Dir Size All menu item sets an option to sum each directory as it is scanned into a Files window. This is identical to the Show Dir Size option except it includes the root directory. It may take considerable time to sum all directories on the drive, hence it is a separate option. The recommended way is to set this option off and use the Files->Get Selected Dir Size option to limit the function to selected directories after the directories are presented in the Files window.
When this option is enabled and all directories are being summed (the root directory is the current directory), a blinking Info Message window appears with the message 'Retrieving size of all subdirectories'. The summing process may be terminated by pressing the Cancel button on the message window.
