File Extensions are components used in File Policies. File extensions match the final right-hand component of a file name.
The file extension here is .doc
This file extension here is .zip
When adding extensions, do not include the . before the extension name.
You may use wildcards. Example: doc*
You may also use pattern matching: pp[ts] will match pps and ppt.
Allow by Default
If selected, this will allow the extension for all existing and new policies.
