Unreal Engine Project Cleaner

A small Windows batch utility for cleaning and regenerating Unreal Engine C++ projects.

Download

Download the latest release

Download ue_project_clean.bat and place it in the root of your Unreal project (next to the .uproject file).

If you work with Unreal Engine C++, you’ve probably done this manually more times than you'd like:

• Delete Binaries
• Delete Intermediate
• Delete Saved
• Regenerate project files
• Reopen the Visual Studio solution

This script automates that entire workflow with a single click.

Cleaning these folders and regenerating project files is one of the most common ways to fix Unreal Engine C++ build errors, broken IntelliSense, and strange compile issues.

What It Does

Clean Unreal build folders safely

The script deletes only folders that Unreal Engine automatically regenerates:

• Binaries
• Intermediate
• Saved

Your source code, assets, and configuration files are untouched.

Cleaning these folders is a common fix for many Unreal Engine problems, including:

• Failed C++ builds
• Corrupted build artifacts
• Broken IntelliSense
• Issues after engine upgrades
• Plugin installation problems

---

Regenerate project files using UnrealBuildTool

The script runs UnrealBuildTool to regenerate project files for your .uproject.

This refreshes your Visual Studio solution so it matches your current code and engine version.

---

Optional automation

The script can also:

• Rebuild the Unreal Editor target
• Automatically open the generated Visual Studio solution

This allows you to go from broken build → clean environment → compiling again in one step.

---

Setup

1. Download the .bat file from the Releases page.
2. Place it in the root of your Unreal project (the same folder as the .uproject file).
3. Open the script and configure:

   set UE_VERSION=5.7
   set UE_INSTALL_PATH=C:\Program Files\Epic Games
   set REBUILD_AFTER=true
   set OPEN_SOLUTION_AFTER=true

4. Double-click the script to clean and regenerate your project.
