So you have installed and uninstalled programs over the years. Did you know you could have dozens or even hundreds of empty folders on your computer. Delete these Folders with Empty Folder Nuker. Empty Folder Nuker deletes empty folders and insures if there are subfolders with files, it skips these folders.
The base folder is the hard drive or a directory you want to check.
It will take some time to scan each drive. Deleting empty folders will optimize your hard drive (especially after defragging).
So what was the result?
You should scan through and make sure you check only folders that are not needed. This program is around 99% accurate. DO NOT DELETE YOUR TEMP FOLDER OR OTHER FOLDERS THAT WARN THEY ARE SYSTEMS FOLDERS.
