What is SUB file?

A .SUB file, also known as the subtitle file, is associated with a digital video file to display the subtitle text for the particular video that is played back. Separate SUB files are supported for different video formats including DivX, MicroDVD, Blu-ray, DVB format. Each of the SUB file contains cue points that provides correct timing sequence to display the subtitle when the associated video is played back. The SUB file is supported in text format and can be edited using a Microsoft Notepad and Microsoft WordPad.

What else may cause problems?

There can be more reasons which determine that you are not able to open the SUB file (apart from the lack of the proper application installed).

First - the SUB file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the SUB file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the SUB file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the SUB file has not been completed and it cannot be opened properly).
