However, if you do happen to use folders, I have a trick I want to show you. One of the deficiencies of folders is that you can have empty folders. Maybe you created one and then before uploading documents were distracted by a phone call or maybe you moved the files somewhere else. Whatever the cause is – empty folders in SharePoint are inevitable. So in case you want to find out if the folder is empty, before clicking on one, there is a trick in the book!
