HJSplit 3.0 for Windows

HJSplit is an application that allows you to split and merge files again. This application is available on Windows, Linux and various other platforms. Why do we need to divide and combine the files? For example, imagine a file with a size of 50 Mb, and try to send to friends, in a newsgroup posting or uploading to websites or FTP servers. It is usually easier to send / receive / download small pieces to manage the entire file at once.
