Good morning everybody! I currently use IsArcx.dll for my setup.exe, but i've noticed a couple of things. When .dll file counts the files included in the .bin file that is being installed, it counts the number of files AND the number of folders included in videogame' directory.
Concerning the total aount of files, it counts the total number of files and the number of folders times the number of total .bin files. Is it like thtat? Why? Is it a bug?

This is an example of how to use ISArcEx.dll with an installer created in Delphi, intended to load the DLL from the temp directory, as requested.

Code:

LibPath := IncludeTrailingPathDelimiter(ExtractFilePath(ParamStr(0))) + 'bin\';



if not Assigned(ISArcExCl) then

  ISArcExCl := TISArcExM.Create(LibPath);

Hello, first of all thank you very much for this wonderful forum I have benefited from it a lot and I apologize if my English is weak, I will talk in detail about the problem I am facing which is: I was working on Redshank[20.08].iss and I was working and compressing files using FreeARC and the following command line:

Quote:

@echo off
freearc a -r -m9 -ep1 -hp -pOceanBox443 OceanData.bin * -xzNewRun.bat
pause

This topic is successful, but I used a more powerful file compression tool "Mini Compressor" and tried compression using the following tools:

Quote:

precomp+nz+static2+XLolz/$bitmapz=bmpz/$bink=bink/$void=void/$photo=jpg/$ogg=ogg/$wavz=wvp/$mp3=mpz

But when exporting the Setup file from Scirpt Inno, I get the clear error in the image :

https://www2.0zz0.com/2025/01/18/08/864756994.png

I tried to add a modification to the arc.ini text:

Quote:

[External compressor : precomp]
header = 0
packcmd = "PreComp\precomp" -cn -intense -ostdout <stdout> $$arcdatafile$$.tmp
unpackcmd = "PreComp\precomp" -ostdout -r stdin <stdin> <stdout>

But I also did not succeed, and this is the closest topic in the forum to solving the problem

What is the packaging tool for "ISArcEx"? I need a tool that can package into .bin format. Can anyone recommend one?

is there any way to unpack multiple archives at once (in parallel) using this?

Think of it like playing music. You can’t play two different songs at the same time using a single player - one has to wait. If you want parallel playback, you need two separate players.
It’s the same here: the unpacking engine works as a single "player". It processes one archive at a time. To unpack multiple archives in parallel, you would need multiple independent instances/processes doing the work simultaneously.
In the context of Inno Setup (and this library), that’s not supported - there’s effectively only one unpacking pipeline, so everything runs sequentially.

p.s. but you need to understand that the processor load is controlled manually. I might update this in the future. (queue).

Поставил 6.3.3 Inno Setup VCL. Пример Example.iss не работал. Нужно добавить DisableWelcomePage=no в секцию [Setup].
Что залито на сайте прикрепил выше.
Сильно много времени не выиграть, так как xtool и так сильно загружает процессор. Больше решает многопоточность и алгоритм.

- Time Management: Intelligent "Time Remaining" and "Elapsed Time"

  tracking with three customizable display formats.

- Process Control: Built-in functions to Suspend, Resume, or Stop

Good morning, i have some issue concerning the new version of IsArcEx.dll. I've made some tests, but anytime i have the "unknown compression method" popup.
Attached a link containing a .bin file and .iss file modified in order to try to decompress .bin file. Bin file has been compressed using DiskSpan and bcm mask.
Where's the problem? Thanks in advance.

In general, the situation is as follows

@BLACKFIRE69
In general, the situation is as follows:

In the new version of IsArcEx, the parameter ISArcExReduceCalcAccuracy does not affect anything at all—at least not the FMX ProgressBar. You can set any values for it, and the progress bar simply ignores them.
The only parameter that visually affects the progress bar and its smoothness is ISArcExCallbackInterval, but the effect only becomes noticeable starting from a value of 55.

In general, the older version was better. There, it was enough to set:

Code:

ISArcExCallbackInterval(5);

ISArcExReduceCalcAccuracy(1);

and everything worked very smoothly.

I hope you can investigate this quickly.

I've added "ISArcExCallbackInterval(5);" instruction for the new version of IsArcEx.dll, but nothing changed.

Any solution? IsArcEx.dll v0.5 doesn't work on .bin files create by DiskSpan.

Good evening. In the third version of the attached image (the one with two blu bars), current time of playing song is always zero. I also think that a mute button would be very confortable. Is it easy to fix?

ISArcEx v0.5 — Update

1 Attachment(s)

ISArcEx v0.5 — Update 02 (LibOnly)

* Bug fixes only. No API changes.

Code:

 - Fixed: `ISArcExReduceCalcAccuracy` did not perform as expected in v0.5

   due to an internal architectural change introduced in this version.

   This has been corrected and the function now behaves as intended again.



 - Fixed: `ISArcExCallbackInterval` silently ignored some values,

   causing progress updates to appear sluggish or unresponsive regardless

   of the configured interval. The valid input range has been restored.



 - Fixed: State inconsistency where accuracy reduction settings could

   behave unpredictably across multiple init calls in the same session.

* Notes:

Code:

- Drop-in library replacement. No script-side changes required.
