Application manager in Workbench 1.0
The bar on the left of the window shows the free space on the floppy disk. Also worth noticing are icons of different sizes (Workbench since the very beginning allowed for every program and document to have its own attached icon of arbitrary size).
This GUI doesn’t have this feature. Workbench has no designated file manager. To view all the files (not only those with icons), one must drop to CLI (Command Line Interface).
