3nity File Splitter and Joiner

Although storage space is less of a concern nowadays, video games, applications, and some specialized file formats can take up a lot of space, making distribution difficult. What’s more, some transfer methods, such as email attachments can impose size limits, and this is where 3nity File Splitter and Joiner comes in handy, to help cut large files into custom chunks.

Split by size, of number of parts

With the application up and running, you can start to add a large by simply dropping it over the main window. Input and output fields are thus automatically filled in, but you can use browse dialog to select a different file, or to create file chunks in a different location. You’re also notified when adding files smaller than 1 MB.
Exact file size is shown just to get an idea of the number of components to generate. Splitting is done according to one of two methods. One of them is used to specify volume size in MB, with several preset value fields, or possibility to write your own. On the other hand, there’s the option to specify the total number you want to split to, with size automatically configured.

Easy merging, and checksum calculator

Joining them back together requires a lot less effort. For instance, it’s enough to simply run the first part, with the application being brought up in the Join tab. If triggered this way, first file path and output directory fields are filled in, with the possibility to change save path, as well as name of the new file. If one of the pieces is missing, joining is not possible.
The application comes with another component to help in this regard, especially when transferring chunks over the web. Dragging a file over the dedicated field, or using the browse dialog to select any kind of file automatically shows its MD5 signature. Sadly, there’s no compare option, so you need to manually save checksums is needed later on.

On an ending note

All things considered, we come to the conclusion that 3nity File Splitter and Joiner is sure to come in handy when you need to send files using a service with size limitations. Both processes require little effort, and are easy to comprehend, while the MD5 checksum calculator lets you know whether the join file is healthy.
