Four Easy Ways to Open CUB Files

The scenario: You have a file with the CUB file extension on your computer that you need to open. You double-click it as usual, expecting for a program to load it up, but sadly nothing happens. You try it again, but still nothing happens. What can you do? Try these four easy methods to open a troublesome CUB file.

1st Method: Open it in another program.

When you double-click CUB files, your computer attempts to open it in a program associated with CUB files. If there’s no program associated with CUB files on your computer, the file won’t open. To open the file, download one of the most popular programs associated with CUB files such as Cubloc Studio PLC Information File, PowerPlay File, or SeeYou Airspace.

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