This feature is only available in Professional and Enterprise Editions.
You have the option to let Identity Finder search only the file types you specify. To open or modify these options, use the Searching Only Common Files versus Some or All Files feature by clicking the Settings button on the Tools and Options ribbon, and selecting File Search from the menu on the left. Then choose Custom file type list and click the Manage button.
The first time you open this window, there is already a list of file extensions. This list includes all the file types that Identity Finder can search automatically with an internal filter, a default Windows IFilter, or an IFilter that you have installed. The items that are already checked represent the list of extensions that are searched when Only common file types is selected. The entire list represents the list of extensions that are searched when All filterable file types is selected. You may remove an extension by highlighting it and clicking the Remove button or disable it but leave it in the list, by deselecting its checkbox. You may add extensions by typing the extension without the dot (.) and clicking the Add button.
The extension list can be behave as an Include list or an Exclude list. This means that Identity Finder will search all extensions with a check, if you have the Include radio button selected. However, Identity Finder will search every file on your computer except the ones with a check, if you have the Exclude radio button selected.
At any time you may click the Restore button to remove any changes you have made and restore the original list of filterable files.
Note: If you would like to override the default filter that is used for searching files click the Override button. For example, you might want to add additional extensions to be considered text, such as *.bak. In this case you may override default search filters so that those file types are treated as text. See the Override Default Search Filters help topic for more information.
To view or change these settings, click the Settings button on the Tools and Options ribbon.
