Not all of them, unfortunately. I have a couple of shortcuts pointing
to batch files, and I haven't found a way to pin them to the task bar.
I was thinking (or not thinking
) of shortcuts to programs, and
obviously forgot about broader uses...
In response to your remark, I just added a toolbar to my taskbar, which
happens (by random choice) to be a folder that contains a manual I
downloaded. And then another folder, and another. The last one is the
gadgets folder, and it even has a subfolder.
These were done by right clicking on the taskbar, then clicking on Toolbars
in the pop-up menu, and then clicking on New Toolbar. I then chose the
above few folders at random just to see how it would go.
It isn't pretty, and I strongly suspect it wouldn't be quite what you want.
If instead I just drag a folder from Windows Explorer to the taskbar, it
gets pinned inside the menu that pops up from the Windows Explorer taskbar
icon - possibly not what you want either.
