JJSplit

Some roughly ten years ago, large files had to be split into multiple volumes in order to fit better on disks to share, or even store them. Even though disk space is becoming less of a concern, files too tend to grow in size, thus starting to bring up the same issue. Luckily, you can rely on applications like JJSplit to easily chop files into multiple parts, and join them back together.

The application can run right after download, requiring no installation to work, meaning it can be used on other computer as well. However, it requires Java Runtime Environment to properly function, but using it keeps the target system’s registries intact, thus not affecting the health status of the PC.

You get to use two components which are easily accessed by selecting the corresponding tab. By default, the application opens with the joiner component selected, so you might end up scratching your head for a while, if choosing a target file becomes close to impossible.

Unfortunately, the application doesn’t integrate itself in the context menu for easy trigger of the splitter, and nor can you just drag them over the main window. On the other hand, the selection dialog is easy enough to use, and doesn’t pose any difficulties.

The application automatically fills in the destination folder, matching the source, so be careful not to flood it with too many files. The original files can be automatically removed after splitting is done, but this isn’t a mandatory option. You can split files either by specifying the total number, or writing down the value of a part.

Joining is not that different from the splitter, at least in terms of process configuration. Needless to say that all parts need to be intact for joining to be possible. Like the splitter, you can have all parts removed in the join process.

Taking everything into consideration, we can say that JJSplit is a practical application you can use to quickly split large files into multiple chunks of fixed size, or by writing down the maximum number of files to be created. It’s lightweight, easy to use by anyone, and gets the job done in the blink of an eye.
