CGSF is a command line based program, no gui is currently available. It tends to work much better compressing large files. It is also faster than most other compression algorithms.
To install, download and run install.sh.
sudo sh install.sh
To uninstall, run install.sh again located in the CGSF directory.
sudo sh ~/.local/share/CGSF/install.sh
Encoding takes a file input and a file output arguement.
Ex:
cgsf-encode input.txt output.cgsf
Decoding a file requires a similar process.
Ex:
cgsf-decode input.cgsf output.txt
