AMIB Joiner

AMIB Joiner is a simple and straightforward application designed as a GUI for the copy /b command in MS-DOS. It gives you the possibility to merge together two or more files, regardless of their format.
The tool doesn't implement rich options and it's intuitive enough to be figured out even by users less experienced with such software.

Setup and GUI

Setting it up takes minimal time and effort. As far as the interface is concerned, AMIB Joiner adopts a standard window with a clear-cut structure, where you can get started by adding to the task list the files you wish to join. This can be done with the help of the file browser or drag-and-drop support. Entries can be re-arranged in any order.

Join two or more files into one

The task list shows the name and full path of each item. In order to join all objects, all you have to do is specify the output directory and file name. This creates a new file with no associated extension, so if you're looking to merge two files of the same type, it's necessary to indicate the file type before the merging procedure. Otherwise, this can be later appended in your default file explorer.
Apart from the fact that you can start a new session from scratch, there are no other notable settings available here. Unfortunately, the application doesn't implement options for splitting the file parts, in order to reconstruct the original items.

Evaluation and conclusion

It's equipped with the bare minimum tools for joining multiple files into a single item, whether they have the same or different extensions. However, it's not possible to split the resulted file, so the information can easily become unrecoverable. Nevertheless, you can test AMIB Joiner for yourself, since it's free.
