What is an SC4 file?

SC4 files mostly belong to SimCity 4. The SC4 file format is used in multiple ways.
One common use is for SimCity 4 save files. These files store simulation data such as city layouts, zoning, and resource management details. They hold information to resume a game with a current city or an entire region.
Another use sees SC4 files as voice recording containers. In these cases, the file holds compressed sound data, sometimes created by devices like the DMR1000 Voice Recorder. This use may also relate to audio functions within the game environment.

• SimCity 4 Save: Loads game progress in SimCity 4.
• Voice Recording: Plays back compressed audio data with compatible software.

FilExt.com notes: To open a SC4 file, check its origin. If it is from SimCity 4, use the game to load your save. If it is a voice recording, try an audio player that supports compressed formats. For further details on audio file handling, see the related webpage.

How can I open an SC4 file?

You need a suitable software like SimCity 4 to open an SC4 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your SC4 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SC4 file directly in the browser:. Just drag the file onto this browser window and drop it.

SC4 format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the SC4 files looks like this:

As a file extension, SC4 isn't very common and includes different formats for the applicable programs. The following file formats are most commonly found in SC4 files:

• 30% of all SC4 files belong to SimCity 4 Saved game. These are binary files, so they do not contain words or text. Most of these files are 220 KB to 2 MB in size. The file type was created 10 years ago, but is still used today. Certain words are almost always found in the files, such as DBPF, IDATx and IHDR. A common filename is City - New City (2).sc4 or City - New City.sc4. Such files sometimes refer to tutorial, ciudad and nueva.
• 30% of all SC4 files use the same file format, which can be identified by the letters "00 00 01 1B" at the beginning. These files contain neither text nor words, but only data. The files are 100 KB to 26 MB in size, with a median of 10 MB. The file name 1.sc4 or VOICE01.sc4 is typical for these files.

The remaining 40% of all SC4 files are different files with different signatures, often e.g. Creative Nomad voice audio and RollerCoaster Tycoon Scenario. You can get all the details of your SC4 file by dragging it onto this page or by clicking the button "Choose your .sc4 file to analyze" above.
