Summary
What is Desktop Tool?
Desktop Tool is a toolbar that resides in taskbar.
Its purpose is to provide the same functionalities as Folder View to Desktop View.
In addition, makes it easy to access QTTabBar menus such as Group, Recent Tab, Recent Files, and Application Launcher from taskbar and desktop.
Without Desktop Tool, no Subfolder Menu, nor Media Preview, nor custom coloring, on your desktop.
How to activate Desktop Tool
The main functionality is realized by setting hooks on the desktop and taskbar threads. By default, double-click on the desktop and taskbar show the Desktop Tool Menu.
Desktop Tool Menu

Double-clicks on the desktop or taskbar, then Desktop Tool Menu pops up.
The menu can contain Group, Recent Tab, Recent Files, Application Launcher, and Desktop files.
Each part of the menu can be expanded or shrunken by click on the blue title with arrow.
You can rearrange the parts by dragging titles when they are shrunken.
Suggested Usage
QTPopup.exe is a command line tool to show Desktop Menu. It's useful if its shortcut are placed on the taskbar. Ready-made shortcut files are in the Tools folder (\Program Files\QTTabBar\Tools) so you only have to pin them to the taskbar.
Especially, one with/desktopcontents
option displays contents of your desktop; it would be helpful to access files on the desktop when the entire desktop is covered by a maximized window.
