Re: Moving Mods and the Sims 4 to a D: drive
@ohjosiek Saves, mods, and other user content are stored in Documents > Electronic Arts > The Sims 4 regardless of where the game itself is installed, and Sims 4 won't look for that data anywhere else. To get around this, you can move the Documents directory to D, which is supported by Windows, but please only do this if D is an internal drive; Windows would react badly if Documents were on an external and that external happened to be unplugged at some point.

Or you can use a symbolic link to redirect the Sims 4 folder, or the Electronic Arts folder, to the location of your choice on D:
Please make sure you have the file paths exactly right before doing this; even one space or letter out of place can bork the command.
In either case, make a backup copy of the Sims 4 user folder, or at least the subfolders (like saves and Mods) you wouldn't want to lose, before proceeding. This process is safe if done correctly, but it's easy to mess up the first time you try it.
