Re: Delete Origin cache on a different drive
@kittell17 Let's see if I can cover everything.
1. You never need to delete Origin's cache unless you have issues with Origin or your games. I never do it unless I'm testing something.
2 and 3. The cache files will in their respective directories on C. I have had Origin installed on D since I built this computer and can't find any cache files on D, and this is how it's supposed to work. To move those files to D, you'd need to redirect the directories to D, which I doubt you'd want to do.
4. To access D, keep "show hidden files" on, then click This PC, then D. You'll land in the root folder of D and should be able to see everything there, including any stray files you don't want on D.
5. Origin shouldn't leave anything on C that needs to be cleaned out. If you're keeping legacy installers, you may want to change the location to D (in the same menu where you changed the install location of Origin games). Origin's DownloadCache will still be in C:\ProgramData\Origin, but it should be empty when you're not actually downloading a game.
6. Sims 4 packs are in their respective folders in the game's program files, i.e. d:\Program Files D\Origin Games\The Sims 4. They're labeled by type of pack and order, for example Seasons is EP05.
By the way, when I installed Sims 4, I initially found a separate Program Files (x86) folder on D that Origin created when I installed the game. So if you named your game install folder something else, you might want to have a look around for stray files. These are not the game's program files, more like partial duplicates, and it should be fine to delete them.
7. I'm not sure why you want everything on D and not C (sure, OCD, but programs load faster on an SSD), but it sounds like you have your reasons. Windows supports all that, so it shouldn't cause any issues.
