Claude inject memories automatically in each session, and also retrieves memories whenever needed eg. troubleshooting. But you might wonder where are these memories kept?

The documentation explains well.

Here’s a tldr:

• Auto memory is per-git-repo, machine-local
• If not a repo, then keyed by the folder path
• Default memory stored in ~/.claude/projects/<repo-or-path>/memory/
• All worktrees/subdirs of same repo share one memory dir
• Override with autoMemoryDirectory setting
• Allowed in: user ~/.claude/settings.json, .claude/settings.local.json, managed policy
• Blocked in: project .claude/settings.json (prevents malicious redirection)

Here’s a trick if you have multiple repos yet they are highly related hence you want a shared memory. You can point their project .claude/settings.local.json to same path! Symlinks also work as an alternative.
