Add/Edit File Type Detection Group Dialog Box
Use the Add File Type Detection Group or Edit File Type Detection Group dialog box to create or edit a custom File Type Detection content group.
File Type Detection groups are used to control access to files based on file types. These groups contain definitions of the file types that make up these groups. A file type definition consists of two properties: a file name extension (for example, DOC) and a description (for example, Microsoft Word document). When you apply a rule based on a File Type Detection group, the rule is applied to all file types included in that group.
To create or edit a custom File Type Detection group
1. In the left pane of the dialog box, under Content group, type the name of the new content group in the Name box.
2. In the right pane of the dialog box, under Available Content, select any file type you want to add to the new content group, and then click the left single-arrow button (< ). You can select multiple file types by holding down the SHIFT key or the CTRL key while clicking them. To remove single file types from the content group, use the right single-arrow button (>). To add or remove all available file types to or from the content group at the same time, use the left double-arrow button (<< ) or right double-arrow button (>>). NOTE: You can search the available content database for specific file types by extension or description. You can use wildcards such as asterisks (*) and question marks (?) to search for a specific group of file types. To find a specific file type or specific group of file types, under Available Content, type an extension or description with or without wildcards in the search string, and then click Find. To filter file types, click Filter. To remove the filter, apply it to an empty string. An asterisk (*) replaces an unlimited number of characters. The question mark (?) replaces a single character. You can use these wildcards in any position and in any quantity.
3. Click OK.
