Unreal-Engine-Batch-Cleaner

It's batch. It Cleans. It's unreal.

Clears out those meddelsome upipelinecache files for unreal engine games. Useful for early release titles that go through frequent updates.

Key Features:

• Safe by default - Moves files to a timestamped DELETE_ME folder in your TEMP directory instead of deleting
• --delete flag - Permanently deletes if you want that behavior
• --log flag - Creates ue_cache_cleaner.log in the same directory as the script with detailed timestamps
• Timestamped backups - Each run creates a new folder like DELETE_ME\UE_PipelineCache_20260118_143022
• Recovery - You can inspect or restore files from the DELETE_ME folder if something goes wrong

Setup Instructions:

Save the script:

Copy the script to a .bat file (e.g., CleanUECache.bat) Save it somewhere permanent like C:\Users\ME\Scripts\ or your Documents folder Star the repo. Copy the file manually. Use git clone. You don't have to learn or install git for this.

Set to run at login via Task Scheduler:

• Press Win + R, type taskschd.msc, press Enter
• Click "Create Basic Task" in the right panel
• Name it something like "Clean UE Pipeline Cache"
• Trigger: "When I log on"
• Action: "Start a program"
• Browse to your .bat file
• Check "Open Properties dialog" on the final screen
• In Properties, go to the "General" tab and check "Run with highest privileges"
• Click OK

Alternative - Quick Test:

Just double-click the .bat file anytime to run it manually and see what it finds/deletes.

What it does:

• Searches your entire %LocalAppData% folder for any file named upipelinecache
• Moves or deletes all instances it finds
• Shows you what it moved/deleted

For Task Scheduler setup:

• If you want logging on login, set the arguments field to: --log
• Completely silent, add the --silent argument
• If you want permanent deletion on login: --delete --log
• For "safe mode" (default): leave arguments blank
  • Weakling

The log file will be created in the same folder as the .bat file, so you can review what was found and processed on each run. You can manually clean out old DELETE_ME folders whenever you're confident you don't need them.
