File extensions excluded from scanning

An extension is a part of a file name delimited by a period. An extension defines the type and content of a file. This section of the ThreatSense parameter setup lets you define the types of files to scan.

By default, all files are scanned regardless of their extension. Any extension can be added to the list of files excluded from scanning.

Excluding files is sometimes necessary if scanning certain file types prevents the program that is using certain extensions from running properly. For example, it may be advisable to exclude the .edb, .eml and .tmp extensions when using Microsoft Exchange servers.

Using the Add and Remove buttons, you can allow or prohibit the scanning of specific file extensions. To add a new extension to the list, click Add type the extension into the blank field and click OK. When you select Enter multiple values, you can add multiple file extensions delimited by lines, commas or semicolons. When multiple selection is enabled, extensions will be shown in the list. Select an extension in the list and click Remove to delete that extension from the list. If you want to edit a selected extension click Edit.

The special symbol ? (question mark) can be used. The question mark represents any symbol.


In order to see the exact extension (if any) of a file in a Windows operating system you have to uncheck the Hide extensions for known file types option at Control Panel > Folder Options > View (tab) and apply this change.
