This is remarkably easy to do, but it can also make you feel really blind if you haven’t done it before
I was recently faced with a filling-up SSD that my OS is installed on.
I currently install all of my programs to a typical platter drive with 2 TB, but many programs still put data and folders in your /Users/ folder.
For instance: Unreal Engine 4 likes to use your user folder for /Unreal Projects? and /Unreal Engine/. everytime you download one of their content packs from the marketplace, its adding about 3-4 GB. To combat this, as well as take care of any other programs that use your User folder when your SSD is filling up, here’s what to do:
find and open your User folder, then right click on the folder you want to relocate. Like below I wanted to move the “My Documents” folder onto another drive
just put it where you want it and hit Move, and that’s it!
I have all of my DA:O DLC, Arma 3 missions, savegames, and Unreal projects (though you might wanna re-compile), and indeed everything in that folder is moved. and since it’s done with windows you won’t have to re-point or re-install any of the software to know the folder’s new location.
