HJSplit is able to split and join files of any type and any size.
What about a backup of very large Gigabyte sized files? HJSplit 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.
Of course, HJSplit can join these split parts back together again, so that the original file is restored. Alternatively, you can use HJJoin
for this, which is a tiny and specialized program for joining files.
HJSplit is very reliable, simple, small and easy to use. It does not need any installation or complicated DLLs, it just consists of one '.exe' file.
HJSplit will enable you to split the large file into smaller chunks, which can be much more easily sent and stored.
