In Kad network,there are hundreds of millions of shared resources,among which a considerable part can be rated as questionable information.In order to understand the characteristics of resources,especially questionable ones,in Kad network,the file resources of peers are measured and analyzed using the Kad-network crawler Rainbow.We find that: 1) both the popularity of files and the number of filenames corresponding to a file approximately fit Zipf distribution;2) the severity of questionable files can be judged more accurately using co-occurrence-words in multiple filenames corresponding to the same file-content-hash;3) the questionable resources only occupy 6.34% of random samples,and 74.8% of which are video files.
