Ok, my problem is solved:

Components are defined in records.ini, too.

in case anyone else has this problem at some point:

Code:
[Record1]
Type=FreeArc_Original
Source={src}\Data1a-01.bin
Output={app}\
Disk=1
Size=386.315.748 bytes

[Record2]
Type=FreeArc_Original
Source={src}\Data1b-01.bin
Output={app}\
Disk=1
Component=1
Size=712.924.910 bytes

[InstallerSettings]
SingleDisk=1

Hello, I have been registered for years, and this is my first post.
I have yet conceptual doubts.

1. It is assumed that if I use a codec (or method) from a compressor (example: zlib of xtool), it is because the group of files that I want to compress, most of them have the codec zlib (right?), But in practice, how can I recognize what codecs are used in those files? maybe a scanner?

2. I have seen statements of compression method like:
5rzm = rep:300mb+delta+rzm/$wav=tta/$bmp=bmp/$jpg=jpg/$jpgsolid=precomp+rep:32

What do the characters /$ mean, what function does it meet? I have an idea, but I prefer an explanation.

3. How do we know what size of chunk set in the parameters of a precompressor (or SREP)? or what is the most advisable to use? For example, I want to compress 100 files and each of them weigh between 8 and 64 MB.

Hello, I'm not a very good repacker, but I know some basis...

1 for finding codec:
-experience (after a while you will know that game made by unreal, or by this other kind of editor use the same compression template)
-hexeditor (you can find some signature or some indications like ogg, wave, mpeg ect)
-game scanner tool (you can find it on this forum)
-"monkey test" test this parameter or this and compare results. For some game it takes me days to find the right setup to gain some %

2 masked compression:
$xxx is mean a group
for example $bmp is for "all file in the bmp group"
It can be .bmp .gif . bitmap (you can setup this group in arc.group)
then the method
in you example $wav=tta it means that all file in the "$wav" group will be processed with TTA method
at the begining of the mask you have rzm
It mean that the files who are not in a group or if the method for this file will fail, it will processed by the main method rzm

3. srep
if you use a normal process like diskspangui or similar
the process will first do a solid chunk (like is you use 7zip with store option and 0 compression)
file1+file2+file3+file4... => bigfile
the srep will work on the bigfille
file1+file2+file3+file4=>bigfile=>srep>=bigfile.sr ep
then bigfile processed by srep will be processed by the final compressor

file1+fille2+file3+file4...=> bifile=>srep => bigfile.srep=>lzma2= > archive
In your question, 64mb is the chunk srep will work with.
it's not the size of the final files, its how many partial chunk of "bigfile" it will work in the same time.
big chunk give better results, but slower compression/decompression.
and less computer compatibility (if you decompress this file on a slow computer with low memory it may fail)
lower chunk size lower the deduplication results, faster compression and decompression but bigger final files.
it's more or less a compromise...
this is very linked to the file.
if you try to srep audio or video files you will not find deduplication (same words, same octet combinasion)
but for texture, in some games there is a lot of same structure, same files, you will have a lot of redundancy and it will reduce the file a lot...


the best method is to experiment, test, try and try again

Hi, there aren't any specific tutorials for making repacks. Inno is used for making installers, not the repack itself. Making repacks is based on doing research and gaining experience.

Here's a few tools I would recommend for starting out:

DiskSpan GUI - for compressing, aka making the repacks: https://fileforums.com/showthread.php?t=104507
ASIS - for making the installer, so you can unpack the archive DiskSpan creates: https://fileforums.com/showthread.php?t=99481

Additionally, you can browse the 'Best Compression Methods for 'Specific' Games INDEX' thread, to find out what method works for certain games (https://fileforums.com/showthread.php?t=101639)
