How can I change the default My Documents folder from SSD to HDD, so that everytime I save a documents or data and or download a software from the Internet it will not save on the SSD instead it will save on the HDD auotmatically?
In Windows Explorer expand Documents, right click My Documents, select Properties, go to location tab, select move and pick your new location.
That should handle most applications. Many applications also have the ability to set their own default save location. This would need to be changed from the applications settings if it is not already pointing to a location within My Documents.
