Not sure I know what you mean.
This is coming from having gotten a Flash Memory Drive. When I stick it in the USB, a drive "E" appears in Windows Explorer. I would like to be able to expand the C and E drives in the Folders pane and keep them expanded as I do stuff. I can click on the + boxes by the Drive headings, and get as many folders expanded as I like, but as soon as I click on the heading for E so I can select folders off of it to drag onto the C drive where I want, the C drive collapses and I have to click the + again to open it in the Folder pane so I can do my dragging.
Small potatoes, yes, but .....
