Finding and removing a hard disk's backup files is sometimes aimed only at lewd files, but typically the user expects to find additional kinds as well, like music files, internet visitation records, hidden files, binaries with mismatching extensions, and text files that are of interest to the software's operator. And, because scanning is already running for inappropriate images, you can also run a scan of the other target files as well.

The better porn detection tools have algorithms for detecting documents and testing for known keywords. Analysis starts by seeing if keywords exist in a built-in group of known words which are unsuitable. Items of interest could be inappropriate keyphrases and sex related or adult concepts; coarse language such as racist remarks, articles about violence, hate or such undesirable topics; signs of improper system use; all these can be located and then displayed as the obtained scan results and viewed as a group. Any of them may be assigned for additional checks by the user, and the decision made about the best method for handling unwanted items in the necessary way.
