What are Z31 files and how to open them

Are you having problems opening a Z31 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 Z31 files.

What is a Z31 file?

A .Z31 file is a Split ZIP Archive (part 31) file.

Files with the .Z31 file extension are split ZIP 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 Z31 extension are part 31 of the split ZIP archive. The last part gets the file extension ZIP.

To access the content of the .Z31 file, you will need to have all the archive part files in the same folder and open the last file (with file extension ZIP) with your compression tool. Some tools can also extract the archive if you select the Z01 file, but others will fail, so make it a habit to always open the .ZIP file.
