How to open P7Z file?

The most common problem when using S/MIME Compressed Message is that a specific P7Z is not associated with the program. This causes the file P7Z to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the P7Z 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 Microsoft Outlook

An often overlooked issue is to make sure that Microsoft Outlook is installed on the computer. To do this, enter the name Microsoft Outlook into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support P7Z files.

Programs to open P7Z file

Remember to download programs supporting P7Z files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Outlook with P7Z files

However, it may happen that the application itself does not cause the P7Z file to open in the Microsoft Outlook application, but you can set it manually. 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. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Microsoft Outlook application as the default for handling the P7Z file.

Step 3. Update Microsoft Outlook to the latest version

The fault may also lie with the Microsoft Outlook program, it is possible that S/MIME Compressed Message requires a newer version of the program. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

Step 4. Check for the following problems with the P7Z file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The P7Z file may be unusually small compared to the original file. Usually this applies to P7Z 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 quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our P7Z file. Sometimes virus-infected P7Z files cannot be recovered, so make a backup in advance.
Older version of P7Z 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.
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 option of recovering data from damaged P7Z files. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted P7Z 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. These directories are write-protected to them and it's very hard to fix this problem. It is best to move P7Z to a different directory.
This problem usually affects more complex files. In this case, the P7Z file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the P7Z file again. Some anti-virus or backup software may occupy the P7Z file for a certain period of time. If nothing helps, please reset the device.
