First off there are VERY few LS themes that look like Explorer. Most of us run LS to get away from the look of Explorer so going back really isn't an option for most. There are a few themes out there, like this one LINK, that do what you want. However, you may be very disappointed if you are actually looking for it to work like Explorer.

My best recommendation to you would be to use something along the lines of The Gathering theme. It is very configurable without a whole lot of work and has multiple skins and layouts that it supports.
