What's Wrong?

Version: 1.7196.1.0 OS: Windows 10 App: Claude Cowork Desktop

Issue: On a fresh install, the LocalCache folder grows extremely rapidly. Cache grew from 3 GB to 13.2 GB within a few hours of normal use. After manually clearing LocalCache it returned to 1.73 GB but quickly grew back to 5.87 GB shortly after.

Location of cache: %LOCALAPPDATA%\Packages[Claude folder]\LocalCache

Related existing issues: #22083, #11646

Steps to reproduce:

  1. Fresh install of Claude Cowork Desktop v1.7196.1.0
  2. Open and use the app normally
  3. Check Settings → Apps → Claude → Advanced Options
  4. Cache grows rapidly within hours

Expected behavior: Cache should remain at a reasonable size.

What Should Happen?

Expected behavior: Cache should remain at a reasonable size. Claude should only be using no more than 4 GB
