How to open 7Z.021 file?

The main problem with Split Multi-volume 7-ZIP Compressed Format Archive (part 21) is that the 7Z.021 file is incorrectly associated with programs. This is manifested by the fact that 7Z.021 files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the 7Z.021 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. This can be achieved by typing 7-Zip into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file 7Z.021 with 7-Zip. Below you will find a list of applications that support 7Z.021 files.

Programs to open 7Z.021 file

Remember to download programs supporting 7Z.021 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of 7-Zip with 7Z.021 files

If the application is or has been freshly installed, but the 7Z.021 file still does not use the 7-Zip program, it means no 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. Using the "Change" button we can select the desired program. 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 7Z.021 file with the 7-Zip application.

Step 3. Update 7-Zip to the latest version

If, despite the association of the 7-Zip program with the Split Multi-volume 7-ZIP Compressed Format Archive (part 21) file, the file still does not open, check the program version and possibly update it to the newest 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 7Z.021 file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The 7Z.021 file may be unusually small compared to the original file. This suggests truncating the 7Z.021 file contents when downloading or copying. The only repair option is to download the file again.
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. The scan should cover the entire computer, not only the 7Z.021 file that we want to open. Sometimes virus-infected 7Z.021 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 7Z.021 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 this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular 7Z.021 file corruption. The easiest way to restore the file is from a backup or by contacting Igor Pavlov, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted 7Z.021 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move 7Z.021 to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file 7Z.021 to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
