Files that are corrupted or files that could not be filtered because of problems in a filter DLL are called unfiltered files and can be viewed by issuing the administrative command for unfiltered files. This command issues the query: @Unfiltered=true. The names section of the .idq file must contain:
[Names] Unfiltered (DBTYPE_BOOL) = 49691c90-7e17-101a-a91c-08002b2ecda9 7
This property is not in the list of built-in properties, to prevent nonadministrative users from making this request. Unlike the other queries described here, the unfiltered-files query is not restricted to administrators. It can be controlled by placing an Access Control List (ACL) on the .idq file that defines the unfiltered property.
Note The unfiltered property cannot be used in conjunction with other properties. A query such as @Unfiltered=true and @write >= -1d will return no results.
