This feature is enhanced in Joget DX to support image resizing options
Introduction
File Upload enables you to attach a file to a form.
File uploaded through the File Upload is stored under "[Joget Installation Directory]/wflow/app_formuploads".
How to set to a different storage path?
There are 2 ways you can change the wflow folder path:
1. By adding "-Dwflow.home=PATH" to your JAVA_OPTS when starting tomcat.
2. By setting the "Uploaded File Storage Base Path" option in General Settings.

Figure 2- Remember to click Apply Change and Save the changes.
- To see it working, head back to the App Composer and click the Launch button in the UI column.
- Click on Create a New Expense Claim button on the Dashboard, fill up the necessary details and click Continue Next Screen.
