Configuration will not be saved because the file extension is invalid. Specify .EXP as the file extension.
Source: Data Export Tool
Severity: Warning
Explanation: The Data Export tool allows you to save the settings that you selected in to a data export configuration file (.EXP). The settings that are stored are the inventory components you selected and the query formed for filtering the workstations. If you open an existing .EXP file, the stored settings will be loaded. This error occurs if you do not specify a valid .EXP extension.
Action: Ensure that you specify a valid .EXP extension.
