What are JOINED files and how to open them

Are you having problems opening a JOINED 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 JOINED files.

What is a JOINED file?

Files that contain the .joined file extension are most commonly associated with the HJ-Split file-splitting software application.

HJ-Split is used to take a large file and split it into several smaller files. This particular file splitting software supports files of up to 100GB in size. The purpose of the software is to make it easier for a user to distribute large files over the Internet and via email.

Once the file has been transmitted, the HJ-Split application can re-build the split file volumes into a single file so that the contents of the archive can be retrieved. The rejoined file is then named with the .joined file extension once this occurs.
