UE Rebuilder
Unreal breaks itself more than you'd expect. This tool fixes it in one click instead of fifteen minutes of folder-clicking.
Why This Exists
If you use Unreal long enough, you know the drill. Build worked yesterday, fails today. Linker errors from nowhere. Stale caches pretending to be real data. The engine corrupts its own intermediate files more often than anyone admits.
The fix is always the same: delete Binaries, Intermediate, Saved, regenerate the VS solution, recompile from scratch. It takes about 15 minutes of clicking through folders. I got tired of doing it by hand, so I put it behind one button.
It also does something I wish Unreal did natively: shows you how much disk space each folder is eating. The DerivedDataCache alone grows to gigabytes if you don't watch it. The tool finds it and cleans it. Works on both UE 4.x and 5.x - it auto-detects what you have installed.
Features
Clean Rebuild
Nukes Binaries, Intermediate, and Saved. Regenerates the Visual Studio solution. Kicks off a full recompile. Full wipe and rebuild, but you just click one button.
Backups
Before it deletes anything, it archives your Source, Config, Content, and Plugins folders with a timestamp. Because I deleted something important once and don't want to do that again.
Disk Cleanup
Shows you exactly which folders are eating your disk. The DerivedDataCache is usually the worst offender - it grows silently to gigabytes. One click clears it.
Auto-Detection
Scans your machine and finds every UE installation. Works with 4.x and 5.x. You don't have to tell it where anything is.
Logging
Timestamps every operation. If something goes sideways, you can read the log and see exactly what happened, in order, with times.
Dark UI
Clean dark interface with a live console. You can watch it work. No hidden processes, no mystery progress bars.
