Free File Splitter and Joiner Utilities
The freeware file splitters and joiners on this page allow you to split a file (large or otherwise) into multiple fragments. The utilities can also merge the files back again into the original whole. They are useful if you want to transport a large file, but only have floppy drives, a limited sized USB flash drive, or the like. They can also come in handy if you want to send a file by email, but your email provider, or that of your recipient, limits the sizes of the attachments.
Some of the tools listed also create a checksum of the original file, so that when you rejoin them back together again, you can be verify that your file was unaltered. Note that even if it doesn't create a checksum, you can always get a free MD5 checksum utility to do it for you.
