.CCH File Extension
File Type 1.NET Security Resolution Cache File
What is a CCH file?
File used by Microsoft's .NET Framework, a platform used for running .NET applications; saves Code Access Security (CAS) cached information and is used for resolving the security demands of a .NET application.
The .NET Framework generates CCH files automatically and uses them to resolve CAS functions more quickly. The files are generally named security.config.cch as well as other derivatives of this name.
NOTE: CCH files can be safely deleted, but the .NET Framework will regenerate them. If you delete them, the application will likely run slower until the files are regenerated.
