What are ZX21 files and how to open them

What is a ZX21 file?
A .ZX21 file is a Split ZIPX Archive (part 21) file.
Files with the .ZX21 file extension are split ZIPX archive files, created by WinZIP or compatible tools.
WinZIP and other compression tools take collections of files and compress them into a single archive file, normally 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 ZX21 extension are part 21 of the split ZIPX archive. The last part gets the file extension ZIPX.
To access the content of the .ZX21 file, you will need to have all the archive part files in the same folder and open the last file (with file extension ZIPX) with your compression tool. Some tools can also extract the archive if you select the ZX01 file, but others will fail, so make it a habit to always open the .ZIPX file.
