This Assembly program is for splitting large files (up to 4GB) for easier distribution. (Or if you think you are a spy, you can divide a file up and then encrypt it for security reasons...) Files can be split by either the number of files that you want, the maximum file size, or you can use preset common sizes for floppies, CDs, etc... The main program can Chop and UnChop files and supports file time and attributes preserving and encryption.
