One of the downsides of using Windows is that, as time goes on, a lot of crud builds up in the nooks and crannies, eventually slowing the whole PC down to a crawl. One example of this is the empty folders left behind by things such as uninstalled software and temporary files. A small freeware app called Remove Empty Directories exists to make your PC experience that little bit easier.
RED is a very simple program with a very simple interface. And it should be; deleting empty folders isn't complicated, just tedious and time-consuming.
After installing Remove Empty Directories, you first need to visit the settings and check /uncheck the options, according to your preferences. You can also construct a whitelist of directories and files that the app should leave well alone. Examples include cloud services such as Dropbox and Google Drive, as well as temporary files that apps need in order to be able to operate.
When you have the settings configured to your satisfaction, you will then be asked to choose a directory or drive to scan. Since a lot of people choose to install Windows in the C drive, this is usually the drive with the greatest number of empty folders in it, but of course you can change the drive letter if you wish. All you have to do is click the "browse" button and navigate to the directory or drive's location.
