zip/unzip

Picard · 06 December 2007, 00:06

Is there a program for amiga that can pack files on hd to .zip ? I only have unzip program.What else packing programs are there? I know about lha and dms but they kind of suck.

Graham Humphrey · 06 December 2007, 00:15

Yes, you should be able to get "Zip" from Aminet. (EDIT: here, in fact.)

Also you could try LZX if you haven't already.

StrategyGamer · 06 December 2007, 02:31

lha is better than zip. So if lha sucks then you are gonna be real unhappy with zip.

Amiga version of ZIP sucks. It does not archive subdirectories and files in them.

Compression algorithms are better in LHA.

Nice, well reasoned debate, there.

Hi Picard, yes there is:

http://aminet.net/package/util/arc/Zip

The usage format is:

Zip -r (archive location/name) (files to be archived location/name)

It works fine and it DOES recurse/archive subdirectories if you use that -r switch. It's case sensitive - don't use -R

Yes I was wrong in that. I stand corrected. But I did some tests which is better:

Test performed on 5 files:

Code:

1. 09.DAT             51462 - data file
2. AEROSMITH.iff     301594 - picture file
3. DBM.WcManager2    378368 - music module in DBM format
4. ffmpegPPC        1126616 - executable
5. XM.WeirdOfAchron 2171958 - music module in FastTracker format

    Size of archive/percentage of compression
File            LhA              ZIP       Ratio LhA against ZIP (the smaller, the better)
1            12939/74,9%     12441/76%    1,040
2           270181/10,4%    269622/11%    1,002
3           243517/35,6%    242626/36%    1,003
4           541259/51,9%    517732/54%    1,045
5           873508/59,7%    865851/60%    1,008
Overall    1941400/48,1%   1908184/47%    1,017

Though on my machine LhA performed all the tests much faster.

Bloodwych · 06 December 2007, 13:41

Interesting tests. I'm not surprised lha is faster as it was developed for the Amiga.

I must admit, I tend to always use ZIP for convenience now. Some of the recent lha releases on Aminet have also been a little unreliable, as KG found out when he used to do his WHDLoad packs in lha.

No wonder he switched to ZIP.

mailman · 06 December 2007, 13:47

Well, I stick to LhA 2.1 and don't care about any recent versions. They are not flawless and I don't have time for experiments. Although ZIP is more efficient, on Amiga I still use LhA. Nevertheless I clearly see that better compression algorythms are in ZIP especially when it comes to comparison of the archives I send through the e-mail. It is my main archiver on PC and it is stronger than LhA.

meynaf · 06 December 2007, 15:22

Using zip for its compression level isn't a good choice imho. Just try lzx with -9 option.

adolescent · 06 December 2007, 17:06

Wow, that Zip on Aminet is ooooooold. You can always get current versions at http://www.info-zip.org.

StrategyGamer · 06 December 2007, 21:36

Zip isn't more efficient.

Why are you hiding your compression options?

It isn't a "test" when you don't show the options you used!

Graham Humphrey · 06 December 2007, 21:37

Retro-Nerd · 06 December 2007, 21:52

This time it's packer war?

Zip it's more comfortable if you use WinUAE AND a real machine. Who cares about compression rates, there is enough space on Amiga (PC) hdd's these days.

Google does not know the file WeirdOfAchron.

Please place the 5 test files in the zone so I can do proper tests on them.

Take any files of yours and you will get the same results (of course I tested only default options and Amiga version of these archivers). Tomorrow I will upload the files.

StrategyGamer · 06 December 2007, 22:50

The default value on your machine is whatever you set it to for lha.
