DiskSpan GUI

Sorry, typo) I wanted to ask how to understand which library is needed, is there some kind of tool or do I need to test one by one

Hello, could you help me with adding the DiskSpan GUI (nz.exe) compression tool?

Hi everyone,

I’ve been trying to integrate nz.exe with DiskSpan / DSG tools as an external compressor, but I keep running into problems and I haven’t been able to get it working reliably.

I attempted various configurations and tried to follow advice from ChatGPT, but unfortunately I am still facing issues. I have tried different method settings, external compressor definitions, and adjustments in both DSG_Arc.ini and DSG_Methods.ini, but I keep running into compatibility or configuration problems — such as “method not supported”, recursive NZ entries, or the GUI crashing.

ChatGPT suggested alternative compressor method approaches that might work with nz.exe, but I’m not sure which one is correct, safe, or recommended in practice. I believe I have explained the situation clearly, but I haven’t been able to resolve the issue myself.

I would greatly appreciate it if someone experienced with DiskSpan / External compressors could review this and suggest stable and working method configurations for using nz.exe. If there are any known working examples of nz.exe integration (especially with DiskSpan 2.0.2.4), that would be extremely helpful.

Thank you in advance for any guidance.


1️⃣ DSG_Arc.ini (ENGINE – THE ACTUAL WORKING PART)

👉 External Compressor Only

[External compressor:nz_ext]
header = 0
solid = 0

packcmd = "FINAL\NZ\nz.exe" a -cO -t0 -m512m -nm $$arcpackedfile$$.nz $$arcdatafile$$
unpackcmd = "FINAL\NZ\nz.exe" x $$arcpackedfile$$.nz

datafile = $$arcdatafile$$
packedfile = $$arcpackedfile$$.nz


✔ No crashes
✔ No recursive effects
✔ DiskSpan compatible

2️⃣ DSG_Methods.ini (GUI – SADECE ETİKET)

👉 NZ Method NOT AVAILABLE
👉 We are adding a preset under ARC

[Method:ARC_NZ]
Name=ARC + NZ (Balanced)
Type=ARC
ExternalCompressor=nz_ext


We can create 3 presets if you want 👇

⚡ FAST
[Method:ARC_NZ_FAST]
Name=ARC + NZ (Fast)
Type=ARC
ExternalCompressor=nz_ext
Options=-cf -t0 -m256m

⚖ BALANCED
[Method:ARC_NZ_BAL]
Name=ARC + NZ (Balanced)
Type=ARC
ExternalCompressor=nz_ext
Options=-cO -t0 -m512m

🧱 MAX
[Method:ARC_NZ_MAX]
Name=ARC + NZ (Max)
Type=ARC
ExternalCompressor=nz_ext
Options=-c> -t8 -m2g


📌 Options→ DiskSpan passes the method name to nz.exe as an additional parameter via ARC. 📌 Since the method name is ARC
, which DiskSpan recognizes, it will not give an error.

3️⃣ HOW DOES DiskSpan APPEAR IN THE GUI?
Compressors
└─ Type ARC
├─ ARC + NZ (Fast)
├─ ARC + NZ (Balanced)
└─ ARC + NZ (Max)


✔ No “method not supported”
✔ No NZ → NZ → NZ loop
✔ No access violation

[wareck]

hello
you have to add in ARC_Standard.ini & ARC_Optimal.ini (installer folder)

[External compressor:nz_ext]
header = 0
solid = 0
unpackcmd = "NZ\nz.exe" x $$arcpackedfile$$.nz

and in DSG_Methods.ini :

[Decomp.NZ]
FINAL\NZ\nz.exe; Destination: NZ\nz.exe;

by the way, NZ is far to lolz / razor / LZMA-MT ratio.
yes can work on old games, but final ratio are not very impressive..

wareck: There are cases where NZ (it doesn't matter which version) definitely beats the LOLZ/RZ duo.

Updated DiskSpan GUI to v2.0.2.4 in the first post.

- Changed the key responsible for informalizing the checksum algorithm within "Records.ini" in the sections intended for the hash file.
  >> Previously the key used was Size=, but from now on there is a new key Algo= for this functionality.
- Added new functionality to DiskSpan GUI that allows generating a hash of the "Data#.bin" file for possible integrity checks of binary files before installation.
  >> The new keys that will store these values ​​in "Records.ini" will be Hash= for the hexadecimal value and Algo= for the algorithm type if it is an algorithm not supported in auto mode.
- Added more oodle libraries to oodle libraries collection. 
- Added compressor descriptions on selection checklist.
- Added final compressor BZip3 to final methods group.
- Fixed some bugs in DiskSpan GUI database methods.
- Fixed user cancellation error displayed in patch creation mode after canceling and restarting patch creation.
- Updated key list for Unreal Engine games (with some news keys).  
- Updated 7-Zip compressor from v24.09 to v26.00 (2026-02-12).
- Updated LZMA SDK compressor from v24.09 to v26.00, (2026-02-12).
- Updated UnRAR.exe/UnRAR.dll decompressor from v7.11 to v7.20 (DLL 7.20.100.1861) (2026.02.04).
  >> The UnRAR.exe x86 (32-bit) version has been discontinued by the developer and will remain at v7.01.0.

- Updated XTool precompressor from v0.8.9 to v0.9.2 (only x64 version)

- Updated "EA Frostbite Engine" plugin to work "bf6" method (clone of the "nfsub").
- Updated DiskSpan GUI database to version 1.1.0.1 (Thanks to KaktoR) (Don't wait for other database updates).
  >> Now with 554 game presets and 35 collection presets (64-bits).
  >> Now with 37 game presets and 8 collection presets (32-bits).

Hello! I was wondering if there are any plans to update DiskSpan GUI to support the latest XTool precompressor v0.9.5? It was released on March 21, 2026 — see: https://fileforums.com/showthread.php?t=102832&page=48

[Cesar82]

The DiskSpan GUI has been updated in the first post.
I ask everyone who downloaded the previous version to delete the DSG and download the new version again from the first post (the file version remains 2.0.2.4).
Several errors related to methods such as those using BMS scripts, among others, have been fixed. Several internal bugs and some visual bugs in full-size mode have also been corrected.

Edit: Fixed checksum module.
Download in first post if replace if your use.

Good evening, i'd like to know how I can compress big files (for example .ucas files in "Banishers Ghosts of New Eden") into several .bin files. I mean: if I try to compress "Banishers Ghosts of New Eden" with LOLZ parameters like ldl5, my RAM (32 GB) will overflow because ldl5 file uses an increasing amount of RAM till overflow! Can I split compressed .ucas files into ucas1.bin, ucas2.bin, ecc instead of a unique ucas.bin file?
Is it a matter of DiskSpan options or anything else?

Lolz memory management is easy, I made repacks on 16GB back in the day before upgrading to 64GB.

Use a smaller dictionary size and be aware of the -tt parameter. Increase your fba to 4096 if needs be. Use fewer threads if needs be.

https://krinkels.org/resources/lolz.264/<-- translate the page to learn all the parameters

[KaktoR]

Natively you cannot do this. You can do the following:
Split the ucas files into several parts before compression and merge them back again after unpacking.
Problem: You will probably miss alot of duplicates from srep.

First of all, thanks to KaktoR and Masquerade for replying me. The combination of parameters I use is as follow:

lolz:dtb1:d512m:mtb96:ldl5:mc1023

It's a very compressing combination, but when I try to compress .archive files in Cyberpunk, .ucas files in Banishers, or .bdt files in Armored Core VI (for example), it overflows my RAM.

So i'm forced to use the following combination:

lolz:dtb1:d512m:mtt1:mc1023

It compresses less then the first, but the pro is no problem with RAM overflow.

Is there a more compressing combination then the second with a constant use of RAM?

You will get lesser compression but better ram usage.
