SCRNCH is a data compressor designed for people, such as software developers, who need to send programs or files to a large number of people cheaply. It provides a high degree of compression and the ability to customize the self-extracting compressed file. SCRNCH takes its time to produce optimal compression, but decompression is automatic and very fast.
