What is the CTA file format?
A file with the .CTA extension is a file known as ColorTouch Assistant Settings. It belongs to the Settings Files category. This format is associated with Venstar Inc..
The reliable way to open a .CTA file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .CTA files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
