What is a .COS2 file?
The file extension .COS2 refers to a type of file known as a Pinnacle Studio Cache File. This file is a temporary file, which means it is not meant to be kept permanently. It is created by certain versions of a video editing software called Pinnacle Studio. This software is used to edit videos, and it creates .COS2 files to store information temporarily for specific resources or media files, such as .WMV (Windows Media Video) or .WMA (Windows Media Audio) files.
When you are editing a video project in Pinnacle Studio, the program automatically generates these .COS2 files. They help the program run more efficiently by storing temporary data that can be quickly accessed during the editing process. However, once you are done editing, these files are no longer needed.
You can open .COS2 files using Corel Pinnacle Studio, which is the program designed to work with them. If you find .COS2 files on your computer and are done with the related video editing project, you can safely delete them. If you need to edit the project again, Pinnacle Studio will automatically recreate any necessary .COS2 files. This means you don't have to worry about losing important data by deleting these temporary files.
