List Name—Type a brief but descriptive name for the approved list. Names must be unique, and will appear in the list when you click HTTP > Configuration > Approved Lists > Filename Lists.

Match—Enter a filename with the desired file extension to match in the field. This field supports the * wildcard. Entries in this field are added one-by-one to the Approved List.

Import approved list—You can import an existing list of filenames that you want to exempt from the file type blocking rules. For example, if you have a list of filenames from Trend Micro's Web site, or filenames that you have compiled using a text editor, you can import the list rather than enter them one-by-one. Imported lists must conform to a defined standard.
