The first thing you should do is just "doubleclick" on the CSPL 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 2. Create association of Firefox with CSPL files

If, despite the installed application, the CSPL file does not start in the Firefox application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CSPL file with the Firefox application.

Step 3. Update Firefox to the latest version

If, however, after binding Firefox with Firefox Data Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Mozilla Corporation website and install the latest version.

Step 4. Check for the following problems with the CSPL file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to CSPL files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our CSPL file. As a result of the scan, sometimes it is not possible to recover CSPL files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CSPL file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair CSPL file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted CSPL files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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. If possible, you can try to move the CSPL file to another location.
This problem usually affects more complex files. 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 CSPL file again. However, some background programs may block the CSPL file while scanning. If nothing helps, please reset the device.
