High rate of file compression

Thank you guys but my question is about settings or how can i get a good
compression rate using 7Zip or any other file compression program to Zip.

few months ago i donwload a driver pack that was 12MB
after i unziped it become 376MB and there was no file conrrupted,
in other words everything was perfect.

i have also seem so many times a 9MB zip files that after decompressing them
they become 195MB.

so once again, my question is about how to get this rate, not about zip anatomy.

Thanks

i mentioned this in my original post. please look at the maximumcompression link and make your selection from there. i also recommended 2 of the best compression utilities known to man

Hello again ,

I when back to that page, yeah in that page everyone is talking about high compression rate,
and bla-bla-bla, but oneone talk about how they done it, what settings they did and so on, etc.
i would like to visit a page where they tell users how the configuration have to be in order to
get this high compression rate.

take a look to this page for example:
http://www.maximumcompression.com/data/summary_mf.php

yeah i got it from the page you posted, but what, talking just about soneone else compression
high rate job and thats all.

i am actually looking for something kind colse of a tutorial.

No magic, depens of data type,see at:http://www.maximumcompression.com/compression_fun.php, says

"Extremely high compression ratio
'What is the best compressor to get really extreme compression?' is a question often asked on the internet. The achieved compression ratio of course depends on the quality of the compressor used, but the type of data that is being compressed is much more important. To show this I created a tiny 115 byte rar file. When you decompress it, it will turn into a textfile of almost 5 MB (a compression ratio of 99.998%). Here it is: test.rar. Note: Turtle 0.07 compresses the same file to 49 bytes, Hook09c (with switches 3 1 1 1) to 36 bytes and UHBC (with switches -b128m -m3) to 24 bytes!!. "

OK, in my case i am not worried about getting the must of compression, but atleast to get
a 570MB reduced to 173MB something like that. or a 30MB reduced to a 9MB.

for a long time i been trying to compress with 7Zip, IZArc, KGB Archiver, UHARC-GUI, etc.
but i have never get any good result with any of them.

for example, i tried compressing with 7Zip a 60MB file, and at the end i get a compressed file
for like 55MB, so what butthers with it if you going to get this?

but at the same time i always see files that i download from the internet with no author name on it
but they have so much ratio compression on it, and thats what always got me thinking and thats
why i don't want to give up till atleast one day i make a compression that i can feel that i done it
with a good ratio even if is not like those who are the master of compression using their time and
effort to compress files that really need time and patience.

cus thats all about when compressing files, yeah, lots of time and patience and atleast 1GB of ram.

But yeah, once again, i still waiting for a tutorial or a tip on how to compress with good ratio.

You have been given the best advice possible.  Understand that some file types are already compressed and cannot be compressed much, if at all, more.

With all due respect, i don't care what that page said, just give me an example thats all.
All i want is a setting in any zip compression program, it doesn't have to be 7Zip or any
of the fancy compressor programs of today.

please don't point to that page anymore, I don't know why people spend time to write that kind of explanation like the one in those pages when what they should be doing is explain to people how
to use those programs to compress files just the way they do it.

three words...

can you doit?

or not

if you know what i am talking about give me an example.

Thanks

Hello GreatGerm,

This post has more meaning, did you read that page? ...i think yes.
