pf course. but this needs to improve fa core because currently algorithms with several output streams arent supported

Squxe, how about testing this version? it should be a bit better than beta

how about testing this version?

I plan update at this weekend

Squxe
great!

Hello everyone,

Thanks Bulat!!!

MONSTER OF COMPRESSION

New Monster of Compression!

Arc.exe is Arc.exe provided in FreeArc-0.40-prerelease2-win32, compressed with UPX3.01(upx_test renamed to Arc.exe)

arc selects compression method by file extension. for files with empty extension it uses ppmd, which is suboptimal, of course. rename test to test.exe and try again

in your second experiment, arc doesn't found arc.groups file and as result it compress everyrthing wih lzma algo

all this is described in doc

Thanks...you're right

but UPX is better than RAR and UHARC(ALZ-3) on that file (at least on my machine)

and good documentation. about 77kb text. good job

FreeArc is most practical compressor/archiver, but it lacks a GUI. someone should write a GUI for it(just like UHARC).

upx, 7-zip and arc uses lzma, which indeed is better than rar and alz-3

But upx produces no real identical files.

yes, upx had advantage that it can use lossy compression and drawback that it should include decompressor too. but this is rather small differences, overall any lzma-based compressor is much better than rar and alz-3

What I know (I didn?t test it myselv yet) UPX is everytime lossy (maybe you have luck sometimes...). I wrote it because I don?t think your archiver wants such a behaviour with the default options

true for win32 executables (tried --exact parameter with 3.01, but was presented with error message saying this exeformat isnt suitable for that)... more about it in this and this forum topic.

I've just published prerelease-3 version. Look at http://sourceforge.net/project/showf...roup_id=207033

Release notes:

This update fixes all known severe bugs, and should be last before the final release. The main task remained now is English version of docs.

I've tested new Tornado algorithm on 1 TB of data and fixed several bugs, now it should be reliable enough for practical usage.

FAR plugin was extended to support archives and files larger than 4 GB.

Total Commander plugin was updated to open archives faster - you should reimport freearc.addon and copy unarc.exe into the PATH.

Definition of external compressors having multiple versions was simplified, look for "ccm" in arc.ini for examples. If you will follow the new style, compressed data will be tagged with exact version of compressor used, which means less confusion when extracting data.

At last, Unix version was added Ctrl-Break handling.

Thanks Bulat!

Great! Thanx, Bulat!

Thank you ->

Best regards!

i've started work on better english trasnaltion of docs. progress i've made so far is on the page http://docs.google.com/Doc?id=dg933c9h_0c8wpgc (or http://docs.google.com/View?docID=dg933c9h_0c8wpgc &revision=_latest for printed version)

my english is far from perfect - please help me in improving readability of the text. if you are ready to participate in this effort - write your address and i will send your google's invitation that allows to edit this document

Hello everyone,

the only hand I could reach out would be "proof-reading", because I do not speak russian sadly
But maybe I could help you with something to add a GUI to FreeArc:
http://tinytools.objective-view.de/Tools/FroG?user lang=en
This is a tool to make GUIs for commandline-programs. It's output is a XML-file which is read at runtime and therefor editable by hand after having created something. Examples included, program itself in english!

Best regards!

Compression times were impressively quick for all modes.

For some reason I can't replicate Werners result of 482,327 bytes for FP.LOG. Using the command line "arc a -m7 -lc160m fp.freearc fp.log" on my machine gives a compressed size of 817,926 bytes.

Can anyone verify this?

I don't have latest version (won't download before release , but have ARC 0.40 (24.10) by Bulat.Ziganshin@gmail.com 24.10.2007

Thanks nimdamsk! I have just realised that "arc.groups" was missing from my test directory.
I will retest and post the results.

Compression speed still very quick for all modes.

Compressing all 10 SFC files into one archive using just "arc a archive.freearc files" as the command line: FreeArc 0.40 created a compressed archive of 10.9 MB (11,503,131 bytes) in just 204.246 seconds.
