Hello,
I am using zip or rzip to compress a 500k file, and zip only compresses it by 9% and rzip by nothing… I reinstalled both of them, and also installed libzip-devel and libzip-util (just in case) and nothing… what am I missing here? I’m running 11.0 64 bit, gnome.
Thanks,
And of what type is the file you want to compress?
The sepcific 500k file is a pdf file, but I’ve tried compressing different types of files, for example mp3, doc or even whole directories, always with the same result. I am using the simplest
zip foo.zip foo.pdf

Files that are already compressed don’t typically compress more very well.
Text files, for example, compress very nicely. mp3 files, by definition,
do not.
Good luck.

Thanks. I checked out with other pdf files and the deflation is around 50%. I am using many images in the file whose deflation rate is 9%, and I’m guessing that might be it… The .pdf files that compress nicely have no images. Does this sound like a reasonable explanation?
Yes, it does.
Thanks Akoellh.
