Hi community   - Disclaimer   - I am not the best when it comes to explaining things to others. So please forgive me. - What is explained here is subject to change (this tutorial will be updated accordingly). - When a tools update is available (on main branch), after having installed the update be sure to verify game cache, extract game datas, and re-install buldozer before trying to do anything else. - The way things are explained here is the way I do it, there are other ways.   - Introduction   In this "tutorial" I will assume that you already have the tools installed (this step won't be explained here) and your directory mapping is the following:    Arma 3 D:\Program Files (x86)\Steam\steamapps\common\Arma 3   Arma 3 Tools D:\Program Files (x86)\Steam\steamapps\common\Arma 3 Tools     - Step 1 - Work Drive Folder   Now we're gonna decide where we want our Work Drive to be located, go to D:\Program Files (x86)\Steam\steamapps\common\ and make a folder here, name it the what you want (mine is Arma 3 Tools [WorkDrive]).   Your Work Drive directory is now the following:   D:\Program Files (x86)\Steam\steamapps\common\Arma 3 Tools [WorkDrive]     - Step 2 - Arma 3 Tools Directory Paths Setup   Now that your Work Drive folder is setup you can now launch Arma 3 Tools from Steam.   Once the window pops up, click on Preferences at the top then click on Options. Here you're going to setup your directory paths.   According to what we previously done, the tabs should look like this:     *Do not forget to uncheck Use default box as in the picture just above*   Now click on Register, and you're done with this step.   - Step 3 - Mounting Work Drive   *Make sure both Arma 3 Tools (Arma3Tools.exe) & Steam (Steam.exe) executable are NOT run as administrator, otherwise your will be unable to mount your Work Drive*   You can now click on Mount the Project Drive to mount your Work Drive, yay.     - Step 4 - Importing Arma 3 Assets   Click on Project Drive Management     Then Extract Game Data     Click on Run.   When prompted, verify information and click Yes.     Once the process is done, you get this:     Now open your Work Drive (Computer -> P:), your drive should look like this now:   *Image coming soon*   - Step 5 - Installing Buldozer   Now you can tick the Install Buldozer box.     Click on Run. Once it's done close the little window and go back to Arma 3 Tools then click on Preferences then Buldozer Configurator. Choose the preset you want for both Object Builder and Terrain Builder then click on Apply configuration. Now open your Work Drive (Computer -> P:), your drive should look like this now:   *Image coming soon*   *While you're at it open steam_appid.txt and verify that its content is 107410*   - Step 6 - Enjoy   Everything is now set up, you can now begin to work on your project.
