It is a convenient place to store everything as it is always visible, but it’s not the best. Most of the time it ends up a disorganized mess even if you sort by name or arrange folders in groups.
Everything on the desktop is scanned on startup. If you have 50 folders on your desktop with tons of files in them it can degrade performance and startup time.
Most important of all, files on the desktop are not as well protected as files in libraries like My Documents and My Pictures. For instance, if you use System Restore to return Windows to its state as of last Wednesday, the feature will remove any files added to the desktop since that date. The files in My Documents will be left untouched.
Folders help you keep your files organized and separate. If you had no folders on your computer, your documents, programs, and operating system files would all be located in the same place.
Organize your files and folders in My Documents and create a shortcut on the desktop to the ones you use most. It will make your life easier.
To create a shortcut simply right click on a folder or a file you’d like to have a shortcut for, select Send to > Desktop (create shortcut)
