1toX is a lightweight tool that lets you divide in parts any file of up to four gigabytes in size and then rejoin them easily. The software can work with several files simultaneously and includes 13 different preset sizes to divide any file you want. That said, you can still enter a different size manually. One of the most interesting options when you're dividing your file into parts is that you can set a password, so if you want to rejoin all the pieces you need to have this program installed, and have the password too. 1toX is quite a useful tool for creating lots of small files that you can rejoin in just a click. Ideal for splitting large files onto different drives.
