What is a CCT file

CCT files mostly belong to Director by Adobe. CCT file format is associated with the Macromedia Director software created by Macromedia and managed later on by Adobe.

  • Use: Director is the main editor on the Adobe Shockwave platform used for developing content such as games, animation sequences, movies and advertisements in the 1990s. Projects developed with the Director application are stored in multiple format such as DIR, DRX, DXR and DCR depending on the operating system and security levels. Each one of the media elements, called as cast, present in these project files such as sound, video, images, text, and buttons are stored separately under the file extension CCT. CCT is a protected file format that ensures that each of the media elements stay unmodified inside a Director project. This allows for the usage of these objects in multiple projects without being modified. Adobe Director was discontinued in both the Windows and MacOS platforms and does not receive updates anymore.
  • Other Uses: MicroSim PCBoard, a PCB software compatible with Windows, uses CCT files to store design information. Microsoft Windows Live Messenger application also uses CCT files for storing contact information of individuals. DesignWorks software uses CCT files to hold schematic data. Railroad Tycoon 3 game uses CCT files to store car type description information.

How to open a CCT file

You need a suitable software like Director to open a CCT 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 CCT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CCT file directly in the browser:. Just drag the file onto this browser window and drop it.

CCT file extension format:

If you know the file format, you can also find out how to open or edit the file. The file format can be deduced from the file extension and the signature. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the CCT files produces the following result:

The CCT file extension is quite common and is used by a few programs, each with its own file format. But the following two file formats are common:

The remaining 35% of all CCT files are different files with different signatures, often, for example, RIFX, XML, attrib, RFSim and Block. They are often associated with human, gene, cptac, tcga, firehose or rsem. Just click the "Choose your .cct file to analyze" button on this page to find out what your CCT file is.

How to solve problems with CCT files

  • Associate the CCT file extension with the correct application.
  • Update your software that should actually open cast resource files. Because only the current version supports the latest CCT file format. Search, therefore, e.g. on the Adobe manufacturer website after an available Director update.
  • To make sure that your CCT file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
