Here’s a thing. I haven’t tried this in other folders but, I have a folder on the hard drive with a number of zip files in it. I configure Windows Explorer to show “Folders” view, i.e. the traditional left pane=tree/right pane=contents view. If I highlight the folder in question, all the files show up in the right hand pane. If I click the “+” symbol to show the contents in the left pane, only some of the files show up there. What’s going on?
