A SIM file contains a "Sim", which is a virtual person created for The Sims 3, an open-ended life simulation game. It stores information about a pre-made or custom Sim person, which includes his or her personality and appearance. SIM files are typically used for sharing with other users and for backing up Sims persons.

More Information

The .SIM file is one of three main file types, along with .PACKAGE and .SIMS3PACK, used in The Sims 3 to contain custom content. SIM files are typically compressed in a .ZIP or .RAR file and need to be decompressed before being installed. There are many programs available to extract archives, such as Apple Archive Utility, Corel WinZip, and PeaZip. After you extract the SIM file from the ZIP or RAR file using a decompression program, place the file in the following directory:

  • Windows XP: C:\​Documents and Settings\​[username]\​My Documents\​Electronic Arts\​The Sims 3\​SavedSims
  • Windows Vista/7/8/10: C:\​Users\​[username]\​Documents\​Electronic Arts\​The Sims 3\​SavedSims
  • macOS: /​Users/​[username]/​Documents/​Electronic Arts/​The Sims 3/​SavedSims

NOTE: If there is no "SavedSims" folder, you can create one.

A SIM file may also be a simulation or video game created by Stagecast Creator, a discontinued visual programming app. It contains all the scripts and assets, such as images or sounds, needed to run the simulation or game. Those who want to edit the simulation or game a SIM file contains must open it with Stagecast Creator. Those who just want to run the simulation or game a SIM file contains can open it with Stagecast Player.

More Information

Stagecast Creator was a multiplatform app used primarily to teach children how to program. In Creator, novice programmers could create animated stories, games, and simulations. These programs were saved as SIM files.

SIM files are re-named .ZIP files, which store all the constituent files necessary to run a program. Those constituent files may be compiled scripts, image assets, audio assets, or other program resources. Notably, the files a SIM file contains do not use file extensions, and most of them are named either iMP### or MP###. Thus, determining exactly which file contains what asset can be difficult and time-consuming.

How to open a SIM file

You can open a SIM file with Stagecast Creator or Stagecast Player. Opening a SIM file with Stagecast Creator allows you to both play and edit the simulation or game the file contains. Opening a SIM file with Stagecast Players allows you only to play the simulation or game the file contains.

To open a SIM file with Stagecast Creator, start the program and select open a sim. Then, navigate to and open your SIM file.

If you want to extract the assets a SIM file contains, you can do so by renaming it to use the .zip extension (instead of .sim) and then opening it as you would any ZIP file.
