You have to use correct zstd library

Use xtool:mzstd:zstd_145

Thanks, it works) Is there a method to understand what the name should be or just test it?

[KaktoR]

What do you mean by "name"?

[Butza]

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

The file naming must contain the value "1" on the right which will be incremented in each slice.
If it does not contain "1", it is necessary to include ".001" so that the slice count is defined.
You can use Data1.bin, Data2.bin, ... Data11.bin, etc only if you use the UNLIMITED tab.

You can also use #a values to increment alphabetically like Data1#a.bin, Data2#a.bin, Data3#a.bin, ... Data10#a.bin, etc.

Hello! I'm have a problem, the data1.bin is not creating, I tried to change tab dvd5 to unlimited it changed to data1.bin from data1.bin.001 but the data1.bin is not creating, here's the summary

I figured it out, making data.bin files must be Ascending order

data1.bin (small files) to....... data4.bin (biggest file

UPDATE:

AFTER 2nd try, it skips the Data1.bin again

Data1 - include *exe *.dll
Data2 - include *.bundle
Data3 - Exclude *.exe *.dll *.bundle

3 data bin has same compression, but it skips data1 again, I tried the reverse it skips again

Your test files were very small (approximately 2 MB), so DSG obtains the size of Setup.dll, and only setupDLL must have exceeded the size defined for DISK1.

If possible, please send me the test files and the DSG_Settings.ini file from the Resources folder of your test, and also a screenshot of the sizes reported as DiskSize where your test failed.

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..

[kj911]

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

[Cesar82]

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.
