Hello, I have to submit an assignment asking for various manipulations regarding archiving and creating *.zip files, etc...
I would like to know two things: how can we obtain information about the compression rate of a file as well as the space gained between the normal file and the compressed one? (simple subtraction?)
In addition, I am asked to convert into .zip, .tar, and .cab. I managed to compress with the first two extensions using Keka, but I can't find any software to compress into .cab...
Thanks :)
