# Global Variables

### General

Global variables allow you to specify [Expressions](/release35/docs/introduction-to-mail-and-deploy-expressions) which can be accessed from any other expression in Mail & Deploy.

          
          

> **Example:** You can create a global variable that holds the root directory path to save report documents to. Every [Save Content To File System Action](/release35/docs/save-content-to-file-system) can access that global variable in order to save reports in that directory (or a sub-directory thereof). If the directory changes you only need to change it once in the global variable.

### Properties

Every global variable has the following properties:

| Name | Description |
| --- | --- |
| Name | The name of the global variable. |
| Value | An [Expressions](/release35/docs/introduction-to-mail-and-deploy-expressions) that returns the value of the global variable. This expression must not contain [Placeholders](/release35/docs/introduction-to-placeholders) except for [Global Variable Value Placeholders](/release35/docs/global-variable-value) referencing other global variables; however you need to make sure that there are no circular references between global variable values. |

### Managing Global Variables

There are two ways to manage global variables:

#### Management Service

You can connect to the [Management Service](/release35/docs/services) of Mail & Deploy and click the *Variables* item in the main menu. This will provide you with a list of all global variables; you can edit or delete existing global variables or create new ones.

#### Report Designer

You can also edit global variables from the [Report Designer](/release35/docs/report-designer) by clicking the button in the main toolbar:
