The main purpose of ZipSplitter is to simplify the tax of copying large files on floppy disks. It also sack be useful if you need to ship large file via email. It splits file on smaller self-restoring parts, i.e. initial file sack be restored without ZipSplitter. This is possible because ZipSplitter adds a very short inscribe (4kb) to the last file, making it executable. ZipSplitter sack compress file before splitting using ZIP concretion, this may significantly decrease the size of the file (you sack function WinZip software to unzip compressed files). Better than WinZip multivolume feature (because you should not rewrite all the diskettes on any error, and you must not receive WinZip on the computer where these diskettes will be take. Very easy to function. Just select "Split with ZipSplitter" from file menu of Windows Explorer.
