I can split the archives using cls-diskspan.dll with freearc but how can i integrate with my installer for decompression ? Would be really gratefull if you could give a example :(

Afair just add the .dll to your script ,like cls-lolz,etc.

I tried many time but always get this is not a freearc archive error

Did you test your archive? (Arc.exe t yourarchive.arc)

Yes I tested there was no issue, Used arc.exe a -i1 -ds -ep1 -r -s; -ed -w.\_Temp -m=diskspan:5mb _Output\data1.bin "_Pack\*" this to create the archives and arc.exe t -i1 -w.\_Temp "_Output\data1.bin" to test it thats why i was looking for an example on how to use diskspan in a installer :(

From where do you got the diskspan library?

There should be an example script.

Got it from DSG , would be really grateful if you could share the link to the one you just said or something similar

If you got it from DSG, there should be a folder named "_Script Example (DSG_Module)".

There you simply compile the script "ISDone_Example.iss" and use the Setup.exe in Output folder to unpack your archive.

It seems pretty complicated, is there no easier way to integrate diskspan to a existing script ? :confused:

Any way to disable second pass on srep? It is it must ?

I think it's mandatory

Sometimes had to face storage issues because of this so thought if it was possible to disable somehow :( anyway thanks for the reply

you may try to use other deduplicator
Like exdude, dedub from panker.

in another way, system work like this :

Original File => decompress/decode => deduplication (try to find repetitions in files) => compression.

On each step you have 2 files

Orignal file and processed file, it is not uncommon to need a lot of disk space during conversion processus.
In another hand SREP do it a lot in memory. only result is stored.
On my computer I've got 32Gb of ram when I do some huge conversion it's more or less all used.

You may try to change :
-vmfile=FILENAME
-slp-


And for finish, if srep hang or crash during second pass => try other version of srep some of them are more stable
Personally, I use 4.90 in 99% of cases.

How common is it in games these days to have 5.1 (or similar) multi-track uncompressed audio tracks?

Is it not at all common or rare? (Usually, mono/stereo audio files occur in games.) A rough example of this in terms of volume is the game Titanfall, with its nearly 35GB of uncompressed audio.

The question would be interesting because according to the statements on the "HydrogenAudio" forum, for multi-channel audio tracks, the TAK codec is much better than FLAC and the like. Does anyone have any experience with compression with this?

Similarly to compressed audio, BINK2 is still the most common video codec, and in the case of games released in the current decade, is it starting to gain ground instead, with videos encoded with x264/x265? (In the case of x264, one could technically talk about lossless recompression, like BPK does with Bink1/2 files.)

Help me find a recompressor for LZMA, .exe archive (100 MB). Made with Inno Setup Data (5.3.6) (u). 100% LZMA is used (for Setup Data and Setup Files, I wrote the unpacker).

I need to unpack an LZMA stream and then pack it into an archive (FreeARC).

I'm doing this for myself; I don't need to create an Installer later.

I tried:
xtool precomp -mzlib+preflate+reflate+lz4+lz4hc+lzo1x+zstd -c1024 MB
precomp.exe -intense -brute
bms2xtl.exe (but bms2xtl.ini says Exclude=lzma_dynamic,snappy)

and many other utilities, but they don't find LZMA streams in this exe.

Finds only quickbms.exe zlb1a.bms.
