Scissors is a tool used to cut binary files into desired size. To cut a file give the source and destination files with the required file size. Any extension given to the destination will be omitted and Scissors will generate required extension automatically with respect to the number of output files. To join these files set any of the fragmented file as input or give filename without extension. Scissors will automatically search and join the files. All files should be in the same directory. The file size fields are ignored in this operation.
