001 Joiner and Splitter Pro is an application that you can easily use to cut files and put them back together. It can be easily used by individuals of any experience level.

The interface of the program is plain and simple to navigate through. You can load a file by using the file browser only, since the "drag and drop" method is not supported. Batch processing is not allowed.

So, when it comes to file splitting, all you have to do is specify the mode (by size or into equal-sized parts) and output directory, in order to proceed with the trimming process.

Furthermore, you can enable 001 Joiner and Splitter Pro to open an Explorer window and to delete the source files after splitting, as well as create a BAT file (in this way, you don't necessarily have to use 001 Joiner and Splitter Pro to join the pieces back together).

The merging process is quite similar. All you have to do is specify the first part of the file and 001 Joiner and Splitter Pro will automatically recognize the rest. Just make sure they are placed in the same folder.

The application takes up a moderate amount of system resources, has a good response time, quickly finishes a task and didn't freeze, crash or pop up errors during our tests. On the other hand, there is no help file available and you cannot configure the program's behavior (e.g. enable 001 Joiner and Splitter Pro to minimize to the system tray). Other than that, we strongly recommend this tool to all users.
