The README, which is written in German, describes a Windows program that helps players install and manage mods across the older and newer Grand Theft Auto games. The author says it covers GTA III, Vice City, San Andreas, IV including Episodes from Liberty City, and V, with support for both the original and Definitive Edition releases. The idea is to give modders one interface for all of these titles instead of separate tools per game. The README lists the file types the manager accepts. These include .asi.dll.cleo.cs.net.dll plugins, RPF archives used by the newer GTAs, and texture files in TXD and DFF formats. Mods can be added by dragging archives such as ZIP, RAR, or 7z into the window. The program keeps profiles for each game, so a player can store several mod setups side by side and switch between them with one click. Safety features described in the README include an automatic backup of any original file before a mod overwrites it, and a vanilla baseline that records the untouched game files so changes can be compared later. For GTA V the program also offers a one-click switch back to vanilla mode, which the author says is meant to keep the GTA Online side of the game safe from mod-related bans. Usage is described as: unzip the download, run GTAModsManager.exe, pick the folder of the game you want to mod, let the program build a baseline, create a profile, drop mods into the window, tick the ones to activate, then start the game normally. Requirements listed are Windows 10 or 11 in 64-bit and about 200 MB of free space. The README is in landing-page style with a prominent download button to an external site, and it does not show source code, build steps, or a licence.
