File Extensions
List of file extensions. Add the file extensions that correspond to the File Extension Filter Type. For example, to accept .csv and .txt files, in the File Extension Filter Type property, select Accept, and then add csv and txt to the list of file extensions.
To add an extension to the list, type the extension in the text box and click Add.
To remove an extension from the list, highlight the extension and click Delete.
