Variables allow you to store and manipulate data and files in your workflows. They can be created by start events, forms, tasks, workflow actions, or automatically created when a workflow is run. For more information, see Variables.

You can set up file handling in your workflow start event An event that triggers a workflow to run when it occurs. An example is Box - New file, which triggers the workflow to run when a new file is uploaded to the specified folder. and actions A tool for building the processes, logic, and direction within workflows. Actions are the steps the workflow performs to complete a process..
Note: Your tenancy's default file storage location must be configured to hold files for later reference by the workflow. This location is used for uploaded files and for files stored as output from actions.

- Start your workflow when a new or updated file is detected in a service; for example, see Box - New file and Connectors.
Store a file reference for use later in the workflow (file share connector start events)

On the Designer canvas, click Start event.
Select a connector from the Start from drop-down list.
Select an event from the Event drop-down list.

- Send and receive files via email; for example, see Assign a task to multiple users
- Manipulate files in services (see Connectors):

- On the Designer canvas, click the action you want to configure.
-
Find the output field for storing the file or set of files.
For example, to store attachments received in task assignee email replies when they may attach multiple files, use the Assign a task to multiple users Multiple file attachments option for the Store output field.
- In the output field, select a variable or specify a file path:
Select a variable. For outputs storing multiple files, select a collection variable. For outputs storing a single file, select a file variable.
Specify a file path. You can use any combination of text and variables, beginning with the root folder. If available, use the folder browse icon
on the right of the path field to navigate to the folder and any subfolders that you want, and then edit the path as desired to include variables and different text.
The availability of variable or path options for storing files varies by action. For more information, see Connectors and Workflow actions.
-
Reference a stored file
For example, reference the new Box file that started the workflow to attach it to a task email notification or reference an image received by the task assignee to generate an invoice document.
- On the Designer canvas, click the action you want to configure.
- Find the field where you want to reference the stored file select a variable or specify a file path:
Select the file variable associated with the stored file. For example, select the variable for the new Box file that started the workflow or select the variable storing Multiple file attachments output from a task action.
Specify the file path where the file is stored. You can use any combination of text and variables, beginning with the root folder. If available, use the folder browse icon
on the right of the path field to navigate to the folder and any subfolders that you want, and then edit the path as desired to include variables and different text.
View example
Both a file variable and a file path are used in the example image below for the Dropbox Business - Copy a file action. A file variable is selected for Source and a file path is specified for Destination.
The variables "CountryVariable" and "Program" insert the values into the file path as determined by earlier workflow logic (in this case, fields in a submitted form). For example, if the person submitting the form selects Australia for country and specifies Inspire2017 for program, then the resulting file path is "/SpecialProgramNDAs/Australia/Inspire2017NDA.docx."
