External Variable Sets
You can use external variable sets to define constants, request variables, session variables, and application variables. External variable sets persist these variables in .xvar files that are located in the user's home folder, outside the project. Multiple projects and flows can reference the same external variable set.
See below for guides to using external variable sets.

Defining Variables in an External Variable Set
Creating an External Variable Set
If you haven't already created an external variable set, select the folder where you want to create the external variable set in the file pane and then click the 
icon in the toolbar for the file pane.
Defining the External Variables
To define the variables in an external variable set, double-click the external variable set in the tree pane. To manage the variables in the Edit External Variables dialog, below, see Editing an External Variable Set under External Variable Sets in the user's guide.
Declaring an External Variable Set
To use an external variable set that you've created, you need to declare the external variable set in the flow: drag the external variable set from the tree pane and drop it anywhere in the flow window.
Note
- After changing an external variable set, you need to propagate the changes to the projects in which you've declared the external variable set: open and then save the projects.
- If you use session variables from an external variable set in a flow, the Flow Service changes the flow's Session property to "Keep."
- To find an external variable set's file path, click the icon in the workspace and open the Basic tab in the inspector. You can find the path in the FilePath property.
Searching External Variable Set References
You can search projects and flows for references to an external variable set or for references to the variables that an external variable set contains. See "Searching" > "Searching External Variable Sets" in the Flow Designer documentation.
