UNITY LIBRARIES CLEANER

This is a Batch Script to free up disk space by emptying the Library folders of your Unity projects. (Don't worry, when you open a project, Unity can always rebuild the content of the Library folder.)

Getting Started

Usage and warnings:

• The .bat file must be placed in a folder containing one or more Unity projects (make sure you have write access for this folder).
• Double-click on the UnityLibrariesCleaner.bat script to make it run.
• If Windows prevents the script from running, click on "More info" and then "Run anyway" (don't take my word for it, take a look at the code first!)
• The script finds all valid Library folders and then offers Manual or Automatic mode.
• Then the contents of the folders are permanently deleted (not placed in the recycle bin).
• The "Library/LastSceneManagerSetup.txt" files are preserved (allows to keep the last open scene of each project). That's it!

Compatibility

• Tested on Windows.

Known Issues

• The script cannot delete files whose path is longer than 260 characters, due to a system limitation. An error message is displayed for each of these files. Files with shorter paths will still be deleted normally. To work around this problem, you must shorten the path of the projects before relaunching the script. (Note that some of Unity features also generate errors when paths are too long, so it's best to always keep your projects in short paths.)
• If the script has a lot of folders to examine, the process may take a long time.

About the Project

• I created this tool to free up some space on my drives, I hope it helps you to claim back your space to!
