Session

One conversation tied to a folder, with its own . See what it is, how it works, how it is used and what to watch for, with pictures and examples.

Back to the glossary Claude Code
Small purple notebooks, each tied to its own folder, with one open and the rest waiting on a shelf.

What it is

A session is one conversation with in one folder. While you work, Claude Code writes every message, tool use and result to a file under ~/.claude/projects/. Because it is saved, you can close the and come back to the same conversation later. Each new session starts with a fresh , so it does not remember earlier sessions unless you use CLAUDE.md or auto .

How it works

  1. Run claude inside your project folder
  2. Talk; saves everything as you go
  3. Exit or run for a new start
  4. Reopen it later with --continue or /resume

How to use it

  1. claude --continue

    reopens the most recent session in the current folder.

  2. claude --resume or /resume

    opens a list of saved sessions so you can pick one.

  3. /rename auth-refactor or claude -n auth-refactor

    gives a session a name so you can find and resume it by that name.

  4. /branch or --fork-session

    copies the conversation into a new session, so you can try another idea and keep the original as it was.

Watch out

Resuming keeps the same session and adds to the old conversation, while branching makes a new ID and leaves the original untouched. Sessions do not share their history, so put rules you always need in CLAUDE.md. The saved transcripts are plain text on your computer, so do not paste secrets into a session.
