KFK Portable

It is common practice for people to send documents via email or various sharing services, but this usually results in failed transfers for very large files.
To avoid such a situation, you can first split the items to smaller parts, and then send them via email, leaving it up to the recipient to merge them back together.
KFK Portable is one of the applications you can rely on to perform both of these tasks, splitting and merging, within a rather simplistic UI.

Portable app for splitting one file at a time

Unlike KFK, the portable edition does not require any installation, and it can be stored on your removable flash drive. This way, you can run it whenever you want to benefit from its functions.
It needs to be mentioned from the get-go that KFK Portable can process only one file at a time, meaning that if you want to split several files, you need to start the process multiple times.

Split files by number of parts or by size

Once you have selected a file (either via drag and drop or by browsing to its location), you also need to specify the output folder.
KFK Portable can split the source file in a certain number of parts, as you choose, or you can enter the size of each part. The application comes with several preset sizes, but you can also enter a custom value if you are not satisfied with the offer.
A special function of KFK Portable is its disk spanning since it allows you to split or rebuild a file using several floppy disks.

Re-create the original file hassle-free

For you to access the contents of a split file, you first need to combine all its parts and generate a single item. Due to KFK Portable, you can also erase the smaller parts once the larger file has been re-created.
All in all, the application can help you split a file, and then rebuild it with as little effort as possible.
