Arc help

[biotec2k8]

I Need a little bit help with the follow Arc Line

a -r -ed -lc512 -ld512 -mt1 -w./ -msrep+delta+lzma:a1:mfbt4:d158m

LC and LD ok....Compression and Decomp Memory

What is DELTA and MFBT4?


I've tried Simple Backup. The tool also does what it should. It packs a directory into a BIN file. The problem is then for me: How do I get the BIN file generated there unpacked again.

I don't know what delta is.

For mfbt4 see this: https://documentation.help/7-Zip/method.htm#MatchFinder

For unpack your bin file use the x command from arc.exe

Example: arc.exe x data.bin -dp.\unpacked

I suggest you to read arc.exe help for more commands.

Edit:

FreeArc uses LZMA, prediction by partial matching, TrueAudio, Tornado and GRzip algorithms with automatic switching by file type. Additionally, it uses filters to further improve compression, including REP (finds repetitions at separations up to 1gb), DICT (dictionary replacements for text), DELTA (improves compression of tables in binary data), BCJ (executables preproccesor) and LZP (removes repetitions in text).

Yes

I have now create a Bat who extract my Test.bin. OK

What are the most popular external packers for Arc and how do I use them effectively?

I would really like to learn that and have been dealing with it for a few days, but somehow I still lack a certain kick

[KaktoR]

"most popular external packers"? Highly depends on what you want to do actually.

I Have FitGirls Game Shady Part Of Me...nice Game...The Compression is great.

I want to understand how it is possible to compress this game very well. I got to 1.10GB. That is a good value. Even if it takes longer to pack. But I am still missing something to get the value of FitGirl.


With a -r -ed -lc2048 -ld2048 -mt1 -w./ -msrep + delta + lzma: a1: mfhc4: d158m I get an approximate value. Ok, it'll take a while. Everything OK. If I understand this compression a little more, I could also try the Inno Setup

[KaktoR]

Well fitgirl got it down to 1gb, that's "just" 100mb smaller then yours. To reach the near same size you probably have to unpack the game files first and do a job there. I don't have the game so I can't tell you anything serious here.

Yes exactly. Now all I need is an adapted arc.ini and these two external compressors. And then I'll test and study it here with me

Very kindly asked: Can someone please create a pack from ARC, an .ini and a pack and Unpack.bat and send it to me?

Thread Moved, if it is not a Game Conversion then it does not belong in the Conversion forum, in future post questions in the Tutorial Sub Forum.

This different results, with variable one -d??? (or without) switches:

Does anyone understand this ??

The best and recommended (file sortings, solid archive) switches from compression?? -ds or -dses or -dsns or without -dxxx??

More examples contains -ep1 switches. My tests, not recommended. This minimal compression ratio differences, available in any external compressors (ex: LOLZ) and multigigabytes ranges? Tested from DLZ and get few kB's gains in few MB's compressed archive. (5466kB vs. 5432kB) without changing the DLZ compressors methods and switches. (Used: slp:d64m:lp0:fb337:cu3:cm43)
