Music, videos, documents, executables and other files become larger and larger while the capacity of floppy disks, CDs, DVDs and e-mail attachments is often limited to a size below your needs. In times where compression is already integrated in most picture, video and sound files, an additional compression as well does not solve this problem so the only chance you have would be to divide a file first, send or copy it to the used media and merge it after that is done again.
But how can you do this? Windows itself offers nothing for it, even CD and DVD burning tools can not help you and e-mail clients can not do it too. The answer comes again from 1-abc.net: Divide any file of any type you like into single files of any size you need.
Merging can as well be done with an unregistered version of this product, so any receiver of your divided files is as well able to get the data joined that you gave him.
