+--------------------
+
+Note that the checksum values for ``md5``, ``sha1``, and ``sha256`` are
+available when
+
+* The command line option ``disable-hashing`` was not used
+* There are no gaps (areas missing)

+Fields
+~~~~~~
+
+
+* "end: The offset of the last byte captured
+* "file_id": Integer value representing the id of a file that has been stored
+* "filename": Name of the file as observed in network traffic
+* "gaps": Boolean value indicating if there were gaps in the file
+* "magic": [optional, requires libmagic] The magic value for the file
+* "md5": Iff closed, md5 sum
+* "sha1": Iff closed, sha1 sum

+* "size": The observed size of the file, in bytes
+* "start": The offset of the first byte captured
+* "state": The state of the file when the record is written
+* "stored": Boolean value indicating whether the file has been stored

+
+Offset values
+^^^^^^^^^^^^^
+
+This example shows the offset values from a ``fileinfo`` event -- note the ``http`` content
+range `start` and `end` value are replicated in the ``fileinfo`` fields::
+
+        http.content_range.raw: bytes 500-1000/146515
+        http.content_range.start: 500
+        http.content_range.end: 1000
+        http.content_range.size: 146515
+        fileinfo.start: 500
+        fileinfo.end: 1000
