1st Method: Open it in another program.

When you double-click CTW files, your computer attempts to open it in a program associated with CTW files. If there’s no program associated with CTW files on your computer, the file won’t open. To open the file, download one of the most popular programs associated with CTW files such as Context Tree Weighting Compressed File.

2nd Method: Take a hint from the file type.
