# Managing Amazon DCV Session storage
<a name="managing-session-storage"></a>

Session storage is a directory on the Amazon DCV server that clients can access when they are connected to a Amazon DCV session.

If session storage is enabled on the Amazon DCV server, you can use the `dcv set-storage-root` command to specify the directory on the server to be used for session storage. For more information about enabling session storage on the Amazon DCV server, see [Enabling session storage](manage-storage.md).

To set the session storage path, use the `dcv set-storage-root` command and specify the session ID and the path to the directory to use.

## Syntax

```
dcv set-storage-root --session session_id /path_to/directory
```

For the directory path, you can use `%home%` to specify the home directory of the user who is currently signed in. For example, the `%home%/storage/` path resolves to `c:\Users\username\storage\` on Windows servers. It resolves to `$HOME/storage/` on Linux servers. 

**Note**  
The `storage-root` value must be an absolute path on macOS.
