# Resuming a Dev Environment
<a name="devenvironment-resume"></a>

The `/projects` directory of a Dev Environment stores the files that are pulled from the source repository and the devfile that is used to configure the Dev Environment. The `/home` directory, which is empty upon Dev Environment creation, stores the files you create while using your Dev Environment. Everything in the `/projects` and `/home` directories of a Dev Environment is stored persistently, so you can stop working in a Dev Environment if you need to switch to another Dev Environment, repository, or project and resume working in your Dev Environment at a later time. 

A Dev Environment will automatically stop if it is idle for the amount of time that was selected in the **Timeout** fields during Dev Environment creation. You must close the AWS Cloud9 browser tab for the Dev Environment to be idle.

**Note**  
The Dev Environment is still available and running even if you delete the branch with which you created the Dev Environment. If you want to resume working in a Dev Environment for which you deleted the branch, create a new branch and push your changes to it.<a name="source-resume-summary-steps"></a>
