The Custom button allows you to specify any folder or set of folders to search. When you choose "Custom", the Custom Folder List dialog box will appear. First, you must enter a folder path to search or click the "..." button to browse for one. Second, click the "Add" button and to add the folder to the Custom Folder List box. For each folder you select, all its subfolders will also be searched. You may add as many additional folders as you wish.
If you would like to specify the folder as an exclusion, click the Add as Exclusion checkbox. This will prevent Identity Finder from searching that specific folder and all its subfolders. A common folder to exclude might be c:\windows.
All the information you enter will be automatically saved to your Personal Information File (PIF). If you want to revert your changes to the last time you saved or clicked OK or Apply, you may press the "Load PIF" button. Your changes will be automatically saved when you click OK or Apply.
