An exception with the FileTypeIdentifier indicates that the indexer was unable to determine the file type, probably due to corruption. The client should review the files to be indexed to be sure that there are no obviously corrupted files, and especially to see if there are any spanned Zip files that are missing a piece. Once the source of the error is located and fixed or deleted, attempt to index again.
