XJoin

XJoin is a simple application designed to split and join files. This type of software comes in handy when you want to cut large files into smaller parts, spread the volumes across multiple devices with a small disk capacity, and reconstruct the original file on another computer.

It's wrapped in a simple interface made from a single window split into two areas, where you can separately join and split files. It's possible to add multiple files from different locations to merge them into a single item, as well as to specify the output directory, file name and format for the new items.

Buttons are available for removing an entry from the list or clearing everything to restart the task. When it comes to file splitting, you can indicate a file, view its current size, set a new size for the new parts, and establish the destination directory to save them in.

It doesn't automatically identify the file extension when merging and cutting files, so you have to type it. After the merging operation, XJoin creates a file whose size is equal to the total size of files in the join list. It gets more complicated when attempting to split files, though. The program doesn't actually create multiple smaller chunks by cutting a file in equal parts. Instead, it creates a single file that contains information extracted from the first part of the large file.

This is why it's difficult to figure out what file types are really supported. For example, the application correctly extracts data from a plain text document, based on the file size you specify. On the other hand, if you try to extract information from a file previously created by joining photos, it creates a file that contains only the first photo from the series, as long as the size you specified is equal or greater than the original image file.

Judging by the observations we made during XJoin's evaluation, this looks more like an unfinished software project. It's best to look for a more reliable file joiner and splitter.
