A system and method for evaluating the integrity of a set of electronically stored files that contain hypertext links or other types of file references. The set of files may be received in compressed or uncompressed form. An integrity evaluator evaluates each file in the set of files for one or more integrity conditions or violations. The integrity evaluator may determine whether any of the files include no references to other files, or are not referenced by any other files. The integrity evaluator may also test for broken references, references employing absolute path names, invalid symbols within references, and other conditions. A report module issues a report regarding the integrity of the files and their references.
