When I put my game into my new computer, I just let it go to C drive. However that drive has less memory than my D drive which is emyty.
Can I just cut and paste the game to D, or do I have to reinszrt the game and tell it to go to D?
Getting error 16 after a few weeks of play.

For Windows OS, you'll have to reinstall the game, and specify the installation folders to go on the D drive. That will only relocate the files out of the Program Files (x86) folder (to the D drive) Your Documents\Electronic Arts\The Sims 3 folder will still be on the C drive. Getting the game to use that folder on another drive is a bit more complicated.

What most with such a setup would want to do, in addition to reinstalling the game program on D, is redirect the entire Documents folder and other such Libraries so that they are actually on D already.

Note that if C is a Solid State Drive (SSD) but D is not, which is a common configuration unless you have two SSDs, then you will no longer get the access speed benefit of the game being installed on or run from the SSD. But small SSDs (less than 256 GB) are really meant to house Windows and related programs/processes, not things like games and game data.

I was afraid of that!
I didn't buy or set up the computer. My husband surprised me!
Now I am getting error 16 due to lack of memory. The C drive has minimal memory; While the d has over 1tg and is empty.
Sorry for spelling, etc. Just diagnosed with cataracts and can't see anything!
So, if I understand, I have to delete the game and put it in D drive?

--Uninstall the entire game. Not "Delete," you can't remove most programs by just deleting files.
--Clean Windows registry with a tool such as Piriform's CCleaner.
--Reinstall on D, SuperPatch to 1.67, etc. This is a disc install rather than Origin, right?
--Redirect your user folders (Documents, etc.) to D -- you may want to pull your TS3 user game folder out first for safekeeping if you have anything in there that you don't want to lose, then put it back once everything is installed again.

Note that on the reinstall you will have to check to make sure your fps rates stay capped, you may need to do this all over again, and your graphics card will again become unrecognized but the same altered sgr files I provided to you before can be put in place on the new install.

I did this in Win7 with symlinks which are explained here https://www.howtogeek.com/howto/16226/c ... -or-linux/

You just need to copy over both folders (program files x86/Electronic Arts, the other in Documents/Electronic Arts) to the new drive and then re-create the Electronic Arts folder as a symlink, pointing to wherever you copied them to.

It's a bit hacky and things can go wrong but it worked for me (Have not tried on win10 admittedly). Definitely faster than reinstalling everything

Yes, symlinks are an alternative. But I think the OP would be better served by doing it the reinstall way. They also likely have no need for their entire Documents library to be on C if the drive is that tight on space, not just thinking about the TS3 user game folder.

So, if I put put back my old folder after re-installing, will that help with the fps since it has the altered sgr files in it?
I have put my game on an external hard drive for safe keeping.

It's good that you parked your current game folder someplace for safekeeping so that nothing can happen to it.

But your use game folder has nothing to do with sgr files or fps capping. The sgr files are in Programs, those will be replaced by the default ones again when you do a reinstall. All you have to do is put the altered versions of the two sgr files I made for you back in place just like you did the first time. They are still up on MediaFire through the link I gave you if you need them again, I never took them down. That will take care of graphics card recognition.

About the fps capping, that is done through the Nvidia Control Panel or Nividia Inspector. I believe (but am not as certain) that you will need to do this again after a reinstall, that doesn't have anything to do with your Documents user game folder either.
