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.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
