Original: Cursor Was Using 50GB of Memory - The Cause Was a Nested `.cursor` Folder

Short summary

Cursor's 50GB+ memory consumption was traced to a misplaced `.cursor` configuration folder nested in a subdirectory instead of the project root. Moving it back to the repository root immediately resolved the issue. Check tool-specific hidden directories when performance suddenly degrades—not just application code.

  • •Nested .cursor folder caused Cursor to consume 50GB+ memory
  • •Solution: move .cursor directory to project root and fully restart Cursor
  • •Lesson: inspect tool configuration directories, not just app code, for performance issues
