Most modern computers have operating systems installed on solid-state drives, referred to as SSD's. SSD's speeds up OS and most application loading times, however, they can be very costly depending on its storage capacity. In addition, constantly writing too much data to an SSD can significantly shorten the drive's lifespan. While The Sims 3 can benefit from increased SSD loading times, file sizes for game saves can be absurdly large… especially when expansion packs, mods, and all kinds of other content are used to customize the game, reading and – especially writing saved game data will eventually degrade load times and overall speed performance of the drive itself. (This can also be problematic for mechanical hard drives (HDD) as well, since they are slower to access large amounts of data. It is advised to purge cached save game files and will touch upon this topic in the Sims Cache Cleaning Script section(s) of this guide.)

It is assumed that Sims 3 and/or Sims 4 is being run from either Windows Vista, 7, 8/8.1 or 10 – but will also work with XP, with slight modifications. Works with Steam, Origin, and DVD installation discs for Sims 3; or with Origin and installation discs for Sims 4.

For whatever reason, the developer decided to hard code Sims 3 saved games to the defaulted Documents folder in Windows (or in My Documents if running XP), making it difficult for the user to choose an alternate saved games location. This tutorial attempts to provide step-by-step instructions to anyone wanting to create a directory symbolic (or soft link) from the defaulted save game location in the Documents folder to the target directory where the actual game saves are stored.

For best performance, it is suggested to have the game installed on an SSD (if possible) and keep game saves on a mechanical drive.

Readers attempting to follow this guide must have proficient working knowledge of Windows operating systems. A high comfort level is necessary when working at the command-line, as well as having familiarity of running an elevated command prompt. Administrative privileges to the operating system is also required.

1. Make sure The Sims 3 game is installed and run it at least once.
   
2. Check your Documents folder to verify the saved game location under Electronic Arts/The Sims folder.
   
   • For some Windows 8.1 users, game saves may be hidden by default. If this is the case, you will need to open the Change the folder and search options under the View tab in Windows Explorer and select Show hidden files, folders, and drives; click the Apply to Folders button, then click OK.
3. Move all existing files inside The Sims folder – including the Sims 3 folder itself and all of its sub-folders to an alternate internal/external drive and folder location.
   
   Note: If moving to a different drive, delete all moved content from the Documents/Electronic Arts folder. (Be sure to create a backup in case anything goes wrong!)
   
4. Open a command prompt as an Administrator.
   
5. In the command prompt, type the following then press Enter:
   
   mklink /J "C:\Users\$USER$\Documents\Electronic Arts\The Sims 3" "G:\Sims3 Game Saves"
   IMPORTANT: $USER$ and G:\Sims3 Game Saves is a Windows username placeholder and suggested drive letter\folder used to demonstrate. Replace with the actual Windows username assigned to the Documents folder, and the drive and folder location you moved your Sims 3 folder and content before running the command.
   
   Note: If running XP, change the Documents location to "C:\Documents and Settings\$USER$\My Documents\Electronic Arts\The Sims 3".
   
6. If done correctly, a command prompt message should look similar to:
   
   Junction created for C:\Users\$USER$\Documents\Electronic Arts\The Sims 3 <<===>> G:\Sims3 Game Saves
   
   Note: If you get an error message saying, "Cannot create a file when that file already exists." check that there are no files or folders inside Documents\Electronic Arts and repeat Step 5.
   
7. Run The Sims 3 again to verify saved games are working correctly.
   Additionally, the Sims 3 folder icon will also show a shortcut arrow from inside the Documents\Electronic Arts folder using Windows Explorer.

Creating a directory junction works exactly as outlined for Sims 3. To create a junction for Sims 4, simply change 3 to 4 in the command prompt as seen in the screenshot below.

If you have lots of custom content loaded into Sims 3 as I do, you will notice that game performance will still degrade – even after having moved the entire saved games folder to a new drive. This is why I have written a couple of batch scripts for Sims 3 that will delete cached save game files and other junk, and will launch the game automatically after the cleaning process… so you won’t have to.

Originally, I included an ultra-condensed (albeit sloppily written) script for Sims 3 in this guide. As I continued to improve automated functionality within the scripts and make them more Origin/physical disc or Steam specific friendly, my primary motivation was to get them working with the Steam overlay no matter which Sims 3 installation type you are running. In doing so, I ended up writing additional guides for each script and have decided to remove the script from this guide to avoid redundancy. (If a simple cache cleaning script without the bells and whistles is preferred, simply copy and paste everything from the first line to the end of the cleaning section in the script for Origin instead.)

📌 If you are running a physical disc and/or Origin installation of Sims 3, then this script can be added to the Origin client. Not only will this script delete saved game cache files, it will launch the Origin client for you (if it’s not already running), followed by the Sims 3 Launcher. In other words, the only tasks you have to do is to run it from the non-Steam game shortcut you made to get the Steam overlay working, load Sims 3 from the Launcher, and manually exit Origin after you close out your game. (Includes a similar script for The Sims 4.)

Note: Includes a stand-alone cache cleaning script option for Sims 3 if it is preferred. The script's comments will explain what is needed to get it working.

📌 Steam players of Sims 3 now has a script specifically made just for it. Since the Steam client resists running batch files, this script can easily be made into a desktop shortcut to bypass the hassle and still automate the same tasks. Like the script for Origin, it automatically cleans the cache for saved games, and will run the Sims 3 Launcher from Steam (it will even start Steam for you if it’s not running already) … and the Steam overlay will still function like normal. In addition, the script also takes care of the launcher bug that occurs in Steam’s version of Sims 3.

It should be noted that if you have more than one installation of Sims 3, there appears to be no significant conflicts – despite Origin and Steam using different versions. Be aware, however, that custom content created by 3rd party creators might not be compatible and display erroneously. (Don’t worry, this is not harmful to the game.) If this is the case and the appearance should bother you, it is recommended to swap out the content with something that displays correctly, and to check which version of Sims 3 that 3rd-party custom content support before adding them to your game.

Like Sims 3, Sims 4 players may also experience performance degradation if the cache isn't cleaned periodically.

Below is a stand-alone cache cleaning script that will work on DVD disc installations as well as Origin. Also runs on Windows versions supporting the Documents folder. (XP users will need to modify this script for My Documents.) This script is not compatible with Mac.

📌 If you prefer having a cache cleaning script that adds the Steam overlay when run through Origin, grab the script here.

Simply run the script before launching Sims 4 or whenever noticing system performance starting to degrade.

• Create a new text file and rename it. (I have named mine Sims4 Cache Cleaner.)
  
• Copy and paste the following into the text file:
  @echo off title Sims 4 Cache Cleaner del /Q "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\localthumbcache.package" del /Q "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\cache\*.cache" del /Q "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\cache\*.dat" del /Q "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\cache\*.jpg" del /Q "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\cachestr\*" if exist "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\onlinethumbnailcache" ( rd /S "%USERPROFILE%\Documents\Electronic Arts\The Sims 4\onlinethumbnailcache" ) else ( echo onlinethumbnailcache folder does not exist. ) echo Cached files deleted. pause exit
  Note:
  For this script, I am using the Windows %USERPROFILE% variable for the game saves Documents folder junction. It will not be necessary to alter this unless you are running Windows XP.
  
• Save and exit the text file.
  
• Change the file extension from .txt to .bat
  
  Note: You will get a warning about changing the file name extension and ask if you want to change it – click Yes.
  
• Double click the file to run.

Optional – for older Sims 4 installs, the cachewebkit and lotcachedata folders are no longer needed. If you feel you may still have these folders, but don't want to delete them manually, copy and paste the following code directly above the echo Cached files deleted. line:
Note: If you are experiencing problems with Sims 4 on Origin and this script does not help improve game performance, clearing the cache for Origin may also help.

Although this has nothing to do with improving computer and Sims 3 performance, I wanted to share this with anyone else experiencing the "Unable to start game. Service Installization failed (0x065d0274)" error in Sims 3.

To fix it, go into the Documents > Electronic Arts folder and rename The Sims 3 folder to The Sims 3 Backup. Afterward, run the game so it will repopulate your game save folders. (If you wish to keep the old game saves in the new folders, copy the backup save files into the corresponding folders... otherwise, delete the repopulated The Sims 3 folder, and rename The Sims 3 Backup folder back to The Sims 3.)

When I originally moved my Sims 3 save games location to another drive, it never occurred to me to take screenshots of the process as I never thought I'd be writing a tutorial for it. Hopefully, I have written this guide well enough that screenshots should not be necessary. As someone who enjoys playing Sims 3, I caved in and bought The Sims 4 during the early Black Friday sale on Origin. After doing some research and some tinkering, I whipped up a quick script and remembered to get a screenshot when I made a directory junction for Sims 4 just to share it with you all.

If you enjoy playing The Sims 4 – and especially Sims 3, as I do, I hope you will find this guide useful.
