You can of course navigate the windows in Explorer to get them so you can see everything side by side, or use a free utility like Cubic Explorer.  

Getting Explorer Windows Side by Side

The process is actually simple but quite useful when looking for a large amount of data. Right-click the Windows Explorer icon on the taskbar and click Windows Explorer.

Our first window opens up and you can certainly drag it over the the right or left side of the screen but the quickest method we’re using is the “Windows Key+Right Arrow” key combo (make sure to hold the Windows key down). Now the Windows is nicely placed on the right side.

Next we want to open the other window, simply right-click the Explorer icon again and click Windows Explorer.

 

Now we have our second window open, and all we need to do this time is use the Windows Key+Left Arrow combination.

There we go! Now you should be able to browse your files a lot more simply than relying on the expanding tree method (as much).

You can actually use this method to snap a window to all four corners of your screen if you don’t feel like dragging it. Once you play with Aero Snap more you may enjoy it, but if you still despise it, you can disable it too!
