Oops, wrong forum. Meant to put it in computers and tech ... I thought I specifically clicked computers and tech. xC









Does anyone know of any amazing compression out there? I tried .7z, but it has proven to be too large for what I am looking for. >.> I've spent the past 4-5 hours tweaking settings in small increments to get the best compression, and the best I could come up with is 20%.

Compressed with this, but individually, the files are like this (based on Archive summary):
1. Length=1220608, Packed Length=480973, Ratio=39%
2. Length=409600, Packed Length=187907, Ratio=45%
3. Length=9154052, Packed Length=1488784, Ratio=16% (MPQs compress really nicely. )
4. Length=557310, Packed Length=182266, Ratio=32%
5. Length=127767, Packed Length=46194, Ratio=36%
(Packed Length=2386124/Length=11469337 = 20.8%)

Complete File:
Length = 11,469,337
Packed Length = 2,325,193 (Slightly smaller than the individual ones added. xD)
Ratio = 20%

I may be able to tweak this more, but it really only shaves off like 1kb.
I'm looking to get it below 2,232,729 (Same files in an MPQ within RAR.)
MPQ within .7z gives 2707KB... which is greater than what I have.

OH SHIIIIIIIIIIIIIIIIII

... Which is exactly why I should have been paying more attention to which forum I clicked. xC



Yay. I compressed it to 1697KB, which is smaller than 2180.4KB.
Still, better compression givegivegive.

Try mpq inside 7z what does that yeild.

It doesn't do much if it is a well compressed MPQ... If it is not a well-compressed MPQ then it compresses it to about what it should be.

.7z is the best compressor I know of. What exactly are you trying to do?

lol 18 hours to compress 1GB of data.

It said very slow on their website...

You could try .tar.bz2 to make sure that any similarities between different files get compressed. Or if you still want to use 7z, you could try making an archive with all of the files added uncompressed, then add that archive into another archive with maximum compression. These are pretty much similar methods, though if you used .tar.bz2 you can use a utility that would treat it as a single compressed archive instead of probably needing a temporary extracted copy.

I think I have good compression... If I have two similar files I can add them at the same time and it will compress to just over the size of one. Also I found a way to compress it a lot by compressing other files inside.
