FileSplitter is a freeware and open source, no frills tool to split up files into a specified number of chunks. Whether you're on dialup and need to transfer large files over the internet without worrying about timeouts or disconnection; want to send that large presentation or document via email or even put that movie file on rapidshare, FileSplitter will chop down your file into more manageable pieces in 4 clicks on your mouse.
Also in the download package is FileUnite which does the exactly the opposite and reconstructs your file. Using exactly the same interface as the splitter means you don't have to learn to use two different tools, plus it automatically deletes all the pieces so you don't need to have 2 times the size of the original file free on your hard drive to unite them.
Both programs feature a progress bar so you can see how far along the current operation is and how long is left until completion. No installation is required, just unzip the downloaded file and you're all set to cut up as good as DJ Jazzy Jeff. FileSplitter is completely free today, tomorrow, in 30 days, next year, forever.
