For a number of years I have been happily using a program called Explorer Plus but lately it has become very slow to load (read and display the root tree etc) and to update file name changes. The program has not been updated for years and the publishers web-site does not even list it any longer. I also have a licenced copy of a program called Explorer2 but I find its interface awkward and some of its features are downright weird (search functions for example) and some features (such as the preview pane) work erratically (see below for attachments showing the problem, if someone can tell me how to correct this I would be very grateful). In fact, I purchased Explorer + because of the issues I was having with X2. Now to the point,,,,,, could someone recommend a good, customizable, Explorer replacement. It should offer dual pane, preview of audio, text, pdf, etc files both in the main interface and in the search results window, as well as quick access to commonly accessed folders (bookmarks or links to particular folders). Being able to customize the layout as well as columns etc is an important requirement. Thanks in advance.
