How to open CTY file?

An often recurring problem with SimCity City Format is that CTY is not associated with the correct program file. Thus, when you open CTY, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the CTY file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install SimCity

The first step is to check if the computer has the SimCity program installed. To do this, enter the name SimCity into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support CTY files.

Programs to open CTY file

Remember to download programs supporting CTY files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of SimCity with CTY files

If, despite the installed application, the CTY file does not start in the SimCity application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the SimCity application as the default for handling the CTY file.

Step 3. Update SimCity to the latest version

The fault may also lie with the SimCity program, it is possible that SimCity City Format requires a newer version of the program. In this case, use the Maxis website or update the program from the application.

Step 4. Check for the following problems with the CTY file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the CTY file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file CTY or the program directory. Sometimes virus-infected CTY files cannot be recovered, so make a backup in advance.
Older version of CTY file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged CTY files. You can restore the file from a backup or use Maxis help.
The program indicates that the file is encrypted or corrupted. The encrypted file CTY except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CTY file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
