HJSplit
HJSplit is a popular set of freeware file-splitting programs created by Freebyte.com in collaboration with various programmers. HJSplit supports many platforms (Windows 3.x/95/98/ME/2000/NT/XP, DOS, Amiga, Java, etc.). All versions are compatible with each other and allow you to exchange files between these different platforms. E.g. a file split on the Amiga can be joined on Windows 2000 and vice versa.
Now what’s the use of a program like HJSplit? Think of a file of 20 Mb, and try to send this to a friend. Using email this does not succeed, it is simply too large, and how to put it onto a floppy? HJSplit will enable you to split the large file into smaller chunks, which can be much more easily sent and stored.
What about a backup of very large Gigabyte sized files? HJSplit (Windows and Java version) also can handle these! E.g. HJSplit allows you to split a 10 Gb file into 640 Mb parts, which can then be stored onto CD-Rom’s by your CD-writer software.
