+# DecDat
+
+DecDat[^1] is a daedalus scripts decompiler orginaly created by [Gottfried](https://forum.worldofplayers.de/forum/members/28709-Gottfried). Its goal is to replace Gothic Sourcer's decompiler, which wouldn't been able to decompile scripts with [Ikarus](../../scripts/extenders/ikarus/index.md) and [LeGo](../../scripts/extenders/lego/index.md). However, that doesn't mean that DecDat is able to produce data that can be compiled again. This tool should be used mainly for research and educational purposes. Source code is available [here](https://github.com/auronen/DecDat/).
+
+## Instalation
+
+The tool is written in Java, allowing it to be executed seamlessly on both Windows and Linux operating systems. To utilize the tool, ensure that Java is installed on your system. We recommend using the Java version available [here](https://adoptium.net/temurin/releases/). Once you have your Java installed, download the latest tool version from GitHub [releases page](https://github.com/auronen/DecDat/releases/), and run the `DecDat.jar` file.
+
+## Usage
+After opening a DecDat you will see a following window.
+

+
+To import a `.DAT` file click at `File -> Open DAT...` select the file encoding, the file itself and optionally `OU.BIN` file if you want to parse dialogues.
+
+And that's it, now you have a `.DAT` file loaded into app, and you can export the code or search for a specific part.

-## Quick overview
+## Features
+
+### Volume compression
+Volumes are compressed using the classic zip algorithm. The zlib library for buffer compression and decompression was taken as a basis. In order for the game to decompress the volume in real time without loss of performance, a special interface [Gratt-5r2/ZippedStream](https://github.com/Gratt-5r2/ZippedStream) was implemented and built into `vdfs32g`. The essence of the interface is that it allows you to pack and read files in blocks of a given size and keep unpacked data in memory in a specific range.
+
+!!! Warning
+    Compresed `.mod` and `.vdf` archives works only with [Union](../../union/index.md) installed.
+
+### Volume optimization
+Optimization refers to the procedure of identifying files with the same content and combining them under a common data source.
+
+### File Explorer Interface
+The program interface has a set of standard file explorer operations - copying, pasting, renaming, searching, etc.
+
+### Drag&Drop
+The function allows you to drag files into the program, as well as pull them out of it. For this function to work correctly, user (administrator) rights must match for the program and Explorer.
+
+### Updating a volume in 1 click
+The program analyzes shared files in the volume and in the game directories (Ctrl + U). If there are physical copies, when you save the volume, updated files will be written to it.
+
+### Opening files directly from a volume
+To avoid wasting time unpacking the volume, double-click on the file of interest, after which it will be opened.
