If you find it tiring to double click your folder or drive name every time you want to open them, here's a solution.
Under the Tools menu inside the Windows Explorer, choose Folder Options, and then in the new dialog window that opens up, check the box next to the “Single – click to open an item (point to Select” option)
That's it, now just by clicking once the folders will pop up.And if you want to revert back your changes, open your folder options again and check the box that reads "Double Click to open and item-Single click to select"
