A folder hierarchy is a structure that you create for the folders on your hard drive, server, or in your Dropbox account. It helps you organize your content in such a way that you can quickly and easily locate the files you’re looking for.
In a folder hierarchy, you create a series of subfolders nested within a main folder. As your system expands, you can break them down into further subfolders, creating a more efficient digital filing system. By giving all your files a designated home, you can make sure it's as easy as possible to find whatever you need, when you need it.
