FileSplitter

Although hard disk drives and even portable storage devices are now capable of storing impressive amounts of data, you might still encounter limitations based on file size, and this can occur in online uploading tasks, such as email attachments. On the bright side of things, you can rely on applications like FileSplitter to cut large files into multiple chunks.

Requires Java to function

One thing you first need to know is that it completely relies on Java Runtime Environment to function, so you need to make sure it’s installed on your computer. FileSplitter doesn’t take you through a setup process, however, meaning it can be carried around on a thumb drive and used directly from it.
As the name clearly points out, you’re able to obtain multiple parts from a large file by the end of an operation. The main window holds a couple of tabs which separate the split and join processes, so you don’t feel overwhelmed. There’s also the possibility to customize the background color by adjusting RGB sliders.

Straightforward split and join operations

Needless to say that one of the first steps is to select the source file, which doesn’t really need to meet any size specifications. Related details are shown in a dedicated section. The destination also needs to be mentioned, as well as the size of each part in MB. Sadly, there’s no list of preset size values to choose from, or the option to specify the target number of parts.
Joining them back together is a little less complicated. You need to select the first file, but all the others need to be under the original name and in the same directory. Sadly, you also need to write down the number of parts to join for the operation to be successful.

In conclusion

All in all, FileSplitter does manage to get the job done in the end, but it feels a little rough around the edges overall. You can only split files by size, and not a custom number of parts, while joining them requires you to know the exact number of parts.
