## Overview

RevokeMsgPatcher is a Windows desktop utility that patches WeChat, QQ, and TIM binaries to prevent message revocation; Weixin builds also expose a multi-instance option. The main workflow is to select a client and installation path, inspect target files and supported patch features, choose applicable categories, then patch or restore backed-up files. The graph separates UI, patch configuration and matching, file modification, and auxiliary tools. Some implementation details are unsampled; those relationships are omitted rather than inferred.

Main entry points: [`RevokeMsgPatcher/FormMain.cs`](https://github.com/huiyadanli/revokemsgpatcher/blob/master/RevokeMsgPatcher/FormMain.cs) (Main patch UI), [`RevokeMsgPatcher/Modifier/AppModifier.cs`](https://github.com/huiyadanli/revokemsgpatcher/blob/master/RevokeMsgPatcher/Modifier/AppModifier.cs) (Patch coordinator), [`RevokeMsgPatcher.MultiInstance/FormMultiInstance.cs`](https://github.com/huiyadanli/revokemsgpatcher/blob/master/RevokeMsgPatcher.MultiInstance/FormMultiInstance.cs) (Multi-instance UI), [`RevokeMsgPatcher/Modifier/FileHexEditor.cs`](https://github.com/huiyadanli/revokemsgpatcher/blob/master/RevokeMsgPatcher/Modifier/FileHexEditor.cs) (Binary file editor)
