What is CPF file?
The file with the extension CPF is the Data Files file type. It was designed by IBM. Data Files consists of 1326 similar files. Cognos Project Format is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows.
How to open CPF file?
An often recurring problem with Cognos Project Format is that CPF is not associated with the correct program file. This causes the file CPF to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the CPF 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 Cognos Business Intelligence
In this case, you should first verify that the Cognos Business Intelligence application is installed on the computer. This can be achieved by typing Cognos Business Intelligence into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support CPF files.
Programs to open CPF file
Remember to download programs supporting CPF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Cognos Business Intelligence with CPF files
However, it may happen that the application itself does not cause the CPF file to open in the Cognos Business Intelligence 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 set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CPF file with the Cognos Business Intelligence application.
Step 3. Update Cognos Business Intelligence to the latest version
The fault may also lie with the Cognos Business Intelligence program, it is possible that Cognos Project Format requires a newer version of the program.
Step 4. Check for the following problems with the CPF file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. Usually this applies to CPF files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the CPF file that we want to open. As a result of the scan, sometimes it is not possible to recover CPF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the CPF 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.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair CPF file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file CPF 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 CPF to a different directory.
This problem only occurs with more complex files. In this case, the CPF file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the CPF file for a certain period of time. If the problem persists, restart the machine.
