What are 021 files and how to open them

Are you having problems opening a 021 file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your 021 files.

What is a 021 file?

A .021 file is a Split 7-Zip Archive (part 21) file.

Files with the .021 file extension are split archive files created by archive and compression applications, in this case most likely 7-Zip.

Compression tools are used to take collections of files and compress them into a single archive file. It is usually done to save hard drive space and to make distributing the file collection easier.

Archive files can get very big, and sometimes it is necessary to split them into smaller parts to fit on CDs or USB drives. When an archive file is split, each part of the archive is assigned a numbered file suffix. Files with the 021 extension are #21 of the split archive.

To access the content of the .021 file, you will need to have all the archive part files in the same folder and open the first file with your compression tool.
