Hello forum,
Could you help me compress GTA 5?
I need a .bat compressor and a very simple script for decompression
nothing overly complicated, just a .bat file and a basic ISDone script
GTA 5 version 1.0.231.0 Folder Size 113 GB
I would like to reach at least 70GB in the end.

Use DiskSpan GUI to compress, loading database config to best compression and use Light Installer Script (LIS) or use ASIS to install the game.

Yes! That’s the one I used, it seems brilliant even though I don’t like having Setup.dll outside the script, but it’s truly a work of art.

Setup.dll is a .arc file containing the necessary decompressors to extract the compression.

1) Alternatively, you can use the "TOOLS" button and go to the "Setup DLL" tab to unpack the setup.dll file. You can then place the extracted files into the "Setup_DLL" folder of your chosen installer and recompile the setup.exe. This will embed the decompressors directly into your setup.exe; however, the extraction process may be slightly slower, and the installer might take longer to launch, as antivirus software will have more internal executable files (within the setup.exe) to scan, which could potentially lead to false-positive virus detections.

2) With certain compatible installers, such as the "Light Installer Script," you can simply place "Setup.dll" in the same directory where the setup.exe will be created, then enable the "#define DSG_InternalDLL" line in the script by removing the ";" at the beginning before compiling the setup.exe. In this configuration, the setup.dll is stored inside the setup.exe and during installation, it is extracted to a temporary folder, from which the decompressors are then loaded, eliminating the need for an external setup.dll file.

P.S: In both cases, you should merge the "records.ini" file into the setup.dll so that an external "records.ini" file is not required.
