What is CA_ file?

The file in the CA_ format belongs to the Compressed Files category. Additionally, the Compressed Files category contains 236 of other files. Microsoft Cabinet Archive Format is supported by 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. The main program that supports this format is 7-Zip. This was created by Igor Pavlov. There are also 7 alternative programs to handle the CA_ file. The Microsoft Windows, WinRAR, StuffIt Deluxe, StuffIt programs will also handle the file when the 7-Zip program does not fulfill its role.

How to open CA_ file?

The most common problem when using Microsoft Cabinet Archive Format is that a specific CA_ is not associated with the program. This causes the file CA_ 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 CA_ 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 7-Zip

An often overlooked issue is to make sure that 7-Zip is installed on the computer. To do this, enter the name 7-Zip into the 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 CA_ files.

Step 2. Create association of 7-Zip with CA_ files

If, despite the installed application, the CA_ file does not start in the 7-Zip application, you must create a file association. 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. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the CA_ file with the 7-Zip program.

Step 3. Update 7-Zip to the latest version

If, however, after binding 7-Zip with Microsoft Cabinet Archive 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 Igor Pavlov website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The CA_ file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CA_ file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file CA_ or the program directory. Sometimes virus-infected CA_ files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the CA_ file. 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. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged CA_ files. You can restore the file from a backup or use help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CA_ 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CA_ file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the CA_ file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
