How to open COS2 file?
The most common problem when using Pinnacle Studio Cache Format is that a specific COS2 is not associated with the program. Thus, when you open COS2, the program selection wizard or some other program starts. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the COS2 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Pinnacle Studio
In this case, you should first verify that the Pinnacle Studio application is installed on the computer. The easiest method is to use the system search engine by entering the program name Pinnacle Studio in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open COS2 files.
Programs to open COS2 file
Remember to download programs supporting COS2 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Pinnacle Studio with COS2 files
However, it may happen that the application itself does not cause the COS2 file to open in the Pinnacle Studio application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the COS2 file with the Pinnacle Studio program.
Step 3. Update Pinnacle Studio to the latest version
If, however, after binding Pinnacle Studio with Pinnacle Studio Cache Format there were still problems, you should update the program to the latest version. In this case, use the Corel Corporation website or update the program from the application.
Step 4. Check for the following problems with the COS2 file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
Very often, the file may be size 0 or incomplete. This suggests truncating the COS2 file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file COS2 or the program directory. Sometimes virus-infected COS2 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the COS2 files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair COS2 file corruption. You can restore the file from a backup or use Pinnacle Systems help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file COS2 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move COS2 to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the COS2 file again. However, some background programs may block the COS2 file while scanning. If the problem persists, restart the machine.
