Question for Precomp

Hi!

How do I use Precomp or PrecompX correctly with FreeArc?

My Arguments are: a -s12g -ep1 -r -ed -lc1024 -ld1024 -mt2 -w./ -mprecomp+srep+lzham.

I can use Precomp on its own, but when I use it with external compressors FreeArc don't use Precomp.

I would like to use Precomp in addition to external compressors. Just how do i do this right?

My Arc.ini:

packcmd = precomp -intense0 -cb {options} -f -o$$arcpackedfile$$.tmp $$arcdatafile$$.tmp

and

packcmd = PrecompX.exe a -c128m -t100p -brute - - <stdin> <stdout>

I certainly did something wrong somewhere

Need Help

Maybe you should use proper english. I can't understand your problem, because of use of german words and meanings in your description (=denglish).

I also saw that many people use LOLZ here. FitGirls uses Xtools in the same way. I can't really use either of them with FreeArc because I can't customize the Arc.ini properly. That would also be another question I would have for the professionals

There's many tools/projects make precomp and other compressors multi threads.

cls-precomp.dll made by BLACKFIRE69 seems to be the most stable one here

https://fileforums.com/showthread.php?t=103690

It calls precomp.exe not precomp32.exe not precomp64.exe
It can set precomp options in cls-precomp.ini

Other ones like MTX+precomp/other compressor crashes often for me, PMT+precomp/other compressor rarely works for me, same thing for PrecompX+precomp

/============

For final compressors, xtor, lolz and lzturbo already has multithread themselves, so I'm not sure if make them mt would have any gain, maybe even slower.

//===========

For other compressors, for example fl2 from
https://fileforums.com/showthread.php?p=483533

It is a very good compressor with good ratio and very fast speed. The exe version can be made multithread with
Universal CLS cls-pexp.dll (multi thread maker)
https://fileforums.com/showthread.php?t=103234
The Universal CLS seems to work great for those compressors like fl2.exe

Universal CLS can also make any other compressor multithreaded hence the name.
However I tried it with precomp, most of the time it works good but occasionally threads might lock up with each other and stuck there for minutes doing nothing before continue. Same thing happens to MTX+precomp but it locks or crash much often.

You'll still have to read, search the forum to learn about how freearc the ini such things

magic = lolz

I don't know why it's called magic, seems pretty pointless to me

Ah yes. Thank you for the info. Is SREP + LOLZ better than SREP + FL2?

I just can't get the same compression rate as Fitgirl Repacks. I try and try and combine different compressors with each other. It almost works. But there is still something missing. Only what?

Fitgirl uses xdelta to reduce the final size. In some cases, it causes the final size to decrease. And he also checks duplicate files.

Read this before using it.

Yesterday I tried Xdelta with Nanozip (NZ). There is not much that can be compressed if the data has previously been processed with Xdelta. But it is also clear. They have already been changed by Xdelta.

I get the best results using Reflate, Srep, Delta. And the end compression with lzham or FL2 compress. Nanozip compresses a little more. Its CM option gets a little more out of there. But then it also takes longer

Reflate is still a very good option for me. However, it also takes a lot longer

Which combination do you use to compress your files?

Xdelta isn't such a compressor. It's a patcher.
For pre-compressed game files,
I often use "xtool + srep + nz / lolz" or "other_pre-compressor + srep + nz / lolz".

For music files, "Mpz+srep".
For any other file, use "srep + nz / rz".

If I've the possibility of using Xdelta somewhere I'll use it too.
