Claude Code reads instructions, settings, skills, subagents, and memory from your project directory and from ~/.claude in your home directory. Commit project files to git to share them with your team; files in ~/.claude are personal configuration that applies across all your projects. On Windows, ~/.claude resolves to %USERPROFILE%\.claude. If you set CLAUDE_CONFIG_DIR, every ~/.claude path on this page lives under that directory instead. Most users only edit CLAUDE.md and settings.json. The rest of the directory is optional: add skills, rules, or subagents as you need them.

Explore the directory

Click files in the tree to see what each one does, when it loads, and an example.

What’s not shown

The explorer covers files you author and edit. A few related files live elsewhere: ~/.claude also holds data Claude Code writes as you work: transcripts, prompt history, file snapshots, caches, and logs. See application data below.

Choose the right file

Different kinds of customization live in different files. Use this table to find where a change belongs.

File reference

This table lists every file the explorer covers. Project-scope files live in your repo under .claude/ (or at the root for CLAUDE.md, .mcp.json, and .worktreeinclude). Global-scope files live in ~/.claude/ and apply across all projects.
Several things can override what you put in these files:
  • Managed settings deployed by your organization take precedence over everything
  • CLI flags like --permission-mode or --settings override settings.json for that session
  • Some environment variables take precedence over their equivalent setting, but this varies: check the environment variables reference for each one
See settings precedence for the full order.

Troubleshoot configuration

If a setting, hook, or file isn’t taking effect, see Debug your configuration for the inspection commands and a symptom-first lookup table.

Application data

Beyond the config you author, ~/.claude holds data Claude Code writes during sessions. These files are plaintext. Anything that passes through a tool lands in a transcript on disk: file contents, command output, pasted text.

Cleaned up automatically

Files in the paths below are deleted on startup once they’re older than cleanupPeriodDays. The default is 30 days. sessions/ holds one small file per running session, used to detect concurrent sessions and crashes. It isn’t part of the age-based sweep: Claude Code removes each file when its session exits and clears crash leftovers on the next launch.

Kept until you delete them

The following paths are not covered by automatic cleanup and persist indefinitely. Other small cache and lock files appear depending on which features you use and are safe to delete.

Plaintext storage

Transcripts and history are not encrypted at rest. OS file permissions are the only protection. If a tool reads a .env file or a command prints a credential, that value is written to projects/<project>/<session>.jsonl. To reduce exposure:
  • Lower cleanupPeriodDays to shorten how long transcripts are kept
  • Set the CLAUDE_CODE_SKIP_PROMPT_HISTORY environment variable to skip writing transcripts and prompt history in any mode. In non-interactive mode, you can instead pass --no-session-persistence alongside -p, or set persistSession: false in the Agent SDK.
  • Use permission rules to deny reads of credential files

Clear local data

Run claude project purge to delete the state Claude Code holds for one project. The command requires Claude Code v2.1.124 or later. It deletes:
  • Transcripts and auto memory under projects/
  • Per-session tasks/, debug/, and file-history/ entries
  • Matching prompt lines in history.jsonl
  • The project’s entry in ~/.claude.json
The command prints the full deletion plan and asks for confirmation before removing anything. The examples below use ~/work/my-repo as a placeholder. Replace it with the path to your project. If no state matches the path, the command prints an error and exits with status 1. Preview the plan without deleting anything:
The plan lists each matching item and why it is included:
Delete with a single confirmation prompt:
The command prints the same plan, then asks Delete 3 item(s) for /home/user/work/my-repo? This cannot be undone. [y/N] and deletes only if you answer y. Omit the path to pick a project from an interactive list. Skip the confirmation prompt for use in scripts:
Pass --all instead of a path to purge state for every project at once, which deletes history.jsonl outright rather than filtering it. Pass -i to step through the deletion plan one item at a time. The command leaves shell-snapshots/ and backups/ alone because those are not project-scoped, and warns about them in the plan output. You can also delete any of the application-data paths above by hand. New sessions are unaffected. The table below shows what you lose for past sessions. Don’t delete ~/.claude.json, ~/.claude/settings.json, or ~/.claude/plugins/: those hold your auth, preferences, and installed plugins.
