check the cls_lolz.dll and cls-lolz_x64.exe file if there exist.
if not copy from Mini Compressor > Resources > ISDone_resource
and paste to your ISDone from Windows Phone Script.

Also ask here (https://fileforums.com/showthread.php?t=93193) to get how to add line to make support with lolz.

nice tool. Can u add lrzip ? also u can test if u want.
bye :)

Its my, not fully tested v0.631 package. Cygwin's variants copy. Not easy find the correct dll's its to running, the lrzip executable. This x86 version. x86_64 (v0.631) exe not working these dll's. This lrzip.exe halfly running from Win XP. Minimum correct Windows version, its probably Win Vista or 7 or Win7 SP1.

gozarck: Checked arc.ini "lrzip" sections: What the -vvf commands?

My tests, its recommended disabling the LZO incompressibility test feature, with use any internal compression, extremely expanding processing time.

example: -z -T -p 2

This understood switches: -N aka nice value. This affect the CR ratio or speed?? Or any? Value: -20...19

This internal FreeArc Recovery records compatible with any externals compressors? Adding a very large percentage or dedicated size recovery record to the archives is against the spirit of competition when repackagers are trying to achieve the smallest possible size.

Last FreeArc supported very tiny 0.01% recovery records adding the archive. (Negligible size, even for large repacks.) See the attached picture.

It is worth reading this, written by Bulat, and also the explanation linked in the first post of the topic, regarding the XZ/LZMA2: https://encode.su/threads/2631-Xz-format-inadequate-for-long-term-archiving?p=50780&viewfull=1#post50780

hi there, I have a problem making a installer for 32bits machines, at first it says it cannot start cls-srep x86 an cls-lolzx86, of course I put the proper executables in Isdone support, but the decompresion fails anyway, saying it cannot write in the disk, any idea?

[kj911]

drzmx: Not a valid Win32 application or "Can't open read file mapping (https://fileforums.com/showthread.php?t=103264)" errors?

First easily solve the linked (https://fileforums.com/showpost.php?p=499386&postcount=14) applications.

Use this: "MakeXP-x86.exe" cls-lolz_x86.exe from patching executables/dll files running from XP.

[drzmx]

no, it can execute and starts decomprension, even can decompress some files, and it just fails, this only happens in x86, in a x64 system it installs fine https://ibb.co/W4VqXqHc

Since you've asked, it only works with Mini Compressor. Somehow it works with other compressors, but somehow it doesn't work between the method Freearc.

Hello, I’ve been using Mini Compressor for a while and overall the compression works great, but I’m having trouble with the self‑extracting (SFX) part.

When I create smaller archives (around 3GB or below), the SFX EXE works normally. It shows the UAC shield icon, Windows recognises it as a valid executable, and it runs without any issues.

However, once the output archive gets larger (somewhere above ~4GB — I don’t know the exact cutoff), the generated SFX becomes invalid. Windows refuses to run it and shows the message “this app can’t run on your PC”. The file also loses the UAC icon, as if the PE header or overlay is broken. The compression itself completes fine — only the final SFX EXE becomes unusable at larger sizes.

I’m not sure if this is a size limitation, a stub limitation, or something in the way the SFX is built.

My second question is more important:
Do I actually need the SFX at all?

If there is a way to extract the ARC file directly — even if it uses Mini Compressor’s extended/“masked” compression chain (LOLZ, SREP64, XTool, Dispack, etc.) — I would prefer that. I don’t mind using command‑line tools or external extractors. I just need a reliable way to unpack the archive without relying on the SFX stub, especially since the stub seems to break at larger sizes.

So my questions are:

Has anyone else seen the SFX EXE become invalid once the archive exceeds a certain size?

Is there a known size limit or PE overlay limit for the Mini Compressor SFX stub?

Is there any tool or method to extract Mini Compressor ARC files directly, without needing the SFX EXE?

If not, is there a patched version of FreeArc or another extractor that supports the extended codecs Mini Compressor uses?

Any help or insight would be appreciated.

[kj911]

SFX and 4GB: This is technically limited, Windows cannot run executable files larger than 4GB. Regardless of whether Windows itself or our EXE file is 32 or 64 bit. I already ran into these limitations when repackaging BMS about 14 years ago. The only way I could overcome this was to get an archive under 4GB in size, thanks to the size of the given ARC archive, a well-chosen set of files and a compression algorithm.

There is only one way to get around this, although I don't know if the SFX stub in Mini Compressor is capable of unpacking the external *.arc archive, if it is next to our SFX file and the file names are the same.

For example, let's rename the classic "freearc-installer.sfx", for example "setup1.exe":

Works:
setup1.exe
setup1.arc

Failed:
setup1.exe
data1.arc

setup1.exe
data\setup1.arc

It may also accept other extensions, the SFX stub.

If the masked compression chain of the given archive is known, you can still get around the problem by creating an installer manually, in CMD or INNOSetup (possibly NSIS). Just make sure you have all the unpacking EXE/DLL files and well-configured cls/arc.ini files. Oh, and what's more important, LOLZ only runs with elevated/administrator rights from the command line under Vista/Win7+, otherwise you'll get CLS error messages. (Under XP, there is usually no such problem. INNO circumvents this by running child processes with elevated/admin rights.)

[Registered55]

Thanks for the breakdown on the 4GB limit and how the SFX stubs handle external archives—that makes complete sense why keeping them separate (setup1.exe + setup1.arc) is the way to go.

To tackle the lack of a native batch mode in the GUI, I’ve been experimenting with a completely hands-off automated approach using a custom PowerShell script. Since I'm aiming for a fully automated pipeline, my script handles things end-to-end: it scans a source directory, groups multi-region variants together so SREP deduplication can process shared assets across builds, dynamically compiles the complex masked compression command string into a temporary batch file, executes FreeArc, and finally triggers Inno Setup to build the companion installer stub right next to the .arc archive.

To be clear, I'm not looking to build any fancy installers or complex setup menus. I literally just want a reliable way to unpack and extract the archive whenever I need it later. From what I understand, because of Mini Compressor's advanced masked compression chain, extraction must be driven through some kind of compiled executable wrapper and cannot be done via a standard right-click "extract here" tool. Is that correct?

While most of my projects have processed and extracted smoothly using this method, I’ve hit one snag on a larger build (an 18GB source ISO compressed down to 13.8GB). This file consistently errors out when extracting at 90.60% every single time at the exact same spot.

Does anyone have any suggestions on what might cause an archive to choke right near the very end like that? Could it be a memory/dictionary allocation limit during extraction, or something that happened during the compression pass? Any advice would be huge!

I'm now in the process of compressing again, this time with a very slight change in the command chain.

the command below is what my script passes over to fa.bat and is from the first run that caused an error with one output project (the other 14 tests are all okay). The second command below is the new tweaked command chain, as maybe the first one was too aggressive perhaps.

I would suspect HALAC* at first, especially if you compress the files in ABC order by extension. That is, the WAV files are right at the end of the unpacking. Why don't you use the MSC+TAK combination? For BMP, and maybe PNGs too, you should get better results with LOLZ instead of GRZip/others. (Without MSC/BMF.) Even if used alone.

My other suspect is the "dispack070", aka "exe2" filter. This is not compatible with DLZ, and may also fail when using other final compressors. (The process stops or crashes at a certain point.) For PNGs, it is completely unnecessary.

I have never used Lepton, I don't know how stable it is. OGGRE may also cause problems.

*This codec, insanely fast! Channels/bit depths supporting limited. (Version depends.)

From my perspective, the SFX has a 4 GB size limit. You have to create your own MC.sfx manually. BUT, you can find the MC_SFX.exe in "Mini Compressor\Resources" folder there.

Before you open MC_SFX.exe, you have to edit the records.ini file first.

[Output]
Folder=your name game

[Record1]
Type=Freearc
Source={src}\Setup-1.arc
Output={app}
Disk=1
Password=yourpassword

And then open MC_SFX.exe; let it finish turning into MC.sfx. Once it finishes, you can find MC.sfx in the "Mini Compressor\Compression" folder. Just rename it from MC.sfx to Setup.exe or MC.exe

One more thing: after you finish making MC.sfx, edit the records.ini file and leave it empty.

Thanks for all the replies. After trying numerous things, I found that the ISO In question compressed with Mini Compressor never extract properly for me. I’ve since switched over to DiskSpan 2, and every profile I’ve tested works smoothly out of the box.

The main reason I'm digging into this is that I want to truly understand how these configurations and execution pipelines work under the hood so I can build a custom PowerShell script. Ideally, I want a robust batch system that treats each subfolder it finds as an independent job.

As for Mini Compressor, I'm no developer, but despite throwing almost every profile at it (including mxx and various other settings) using a clean, latest-version installation, it simply chokes on the PS3 ISO Afrika (BLUS30399). The extraction failure is always predictable rather than random—depending on the settings used, it breaks at specific offsets, which suggests something underlying in Mini Compressor's toolchain or packaging just doesn't agree with that specific image format.

If anyone has insights into mapping these toolchains into a clean PowerShell batch loop for subfolders, I'd love to hear how you set it up!

Thank you kj911 for your suggestions, I have taken on what you said, and although helpful in my approach in this area, regarding this ISO nothing you suggested worked. But he same ISO went though Diskspan 2 fine. I was hoping i could understand the deep mechanics of the profiles, the ARC.ini and FA.ini and the diskspan2 counterpart also, I tried some things trying to understand and match profiles and it's settings from Diskspan2 to Mini Compressor. However in many ways the two system are quite different to one another, and my very limited skills soon started to be an issue, and i got repeated failed execution from the FA.bat I was running.

First off — I’m glad DiskSpan 2 is working smoothly for you! That’s honestly the most important thing: your files get compressed properly and extract without trouble.

About the PS3 ISO Afrika (BLUS30399) — thank you for reporting this so specifically! The fact it fails at consistent offsets tells me it’s not random — something in how Mini Compressor handles that exact ISO structure doesn’t agree with it. I don’t have that ISO to test myself, so this is really valuable info. I’ll keep this in mind and dig into the toolchain when I can.

I totally get your goal too — wanting to understand how the profiles, .ini files, and pipelines work so you can build your own PowerShell/batch system! That’s such a great learning path.

Quick honest note: Mini Compressor is built on FreeArc with a very specific, custom layered setup I’ve put together over time — it’s not just plain FA.bat. That’s why translating settings one-to-one between DiskSpan 2 and MC is tricky — they’re built differently under the hood, different tools, different flow. Trying to match them directly will hit walls because they’re not the same design.

Don’t worry about not getting FA.bat or the profiles right away — these systems are complex by design, and everyone struggles with them at first! You’re already doing great by digging in this deep.

It took the program two hours to compress a 5MB file.
When I set a password for the file, it opens without asking for the password after compression is complete.
Please update the program as soon as possible and fix all the issues.
