# Working with File Revisions in the AWS Cloud9 IDE
<a name="file-revisions"></a>

You can use the **File Revision History** pane in the AWS Cloud9 Integrated Development Environment (IDE) to view and manage changes to a file in an AWS Cloud9 EC2 development environment. The **File Revision History** pane is not available for files in an AWS Cloud9 SSH development environment.

To show the **File Revision History** pane for a file, open the file in the editor. Then, on the menu bar, choose **File, Show File Revision History**.

The **File Revision History** pane begins tracking a file's revision history in the IDE after you first open the file in the editor in an environment, and only for that environment. The **File Revision History** pane tracks a file's revisions only from the editor itself. It does not track a file's revisions made in any other way (for example by the terminal, Git, or other file revision tools).

You cannot edit a file while the **File Revision History** pane is displayed. To hide the pane, choose **File, Show Revision History** again, or choose the **X** (**Close timeslider**) in the corner of the pane.

To jump to a version of the file that is associated with a file save action, choose a **File Saved on** dot above the revision slider.

To go forward or backward one version from the currently selected version of the file on the revision slider, choose one of the step arrows (**Step revision forward** or **Step revision backward**).

To go forward automatically one version of the file at a time from the beginning to end of the revision history, choose the play button (**Playback file history**).

To make the currently selected version of the file the latest version in the revision history, choose **Revert**.
