Syntax: select Exclude or Include
Unknown File Formats controls how files in an unknown format
(e.g. binary content not identified as PDF, Word, text, etc.) are
handled. If set to
Exclude (the default), such unknown
formats' data will be ignored; this avoids bloating the walk database
and query autocomplete dictionary with garbage binary content.
If set to
Include, the data will be included. This might help
find words in otherwise-unsearchable binary files, but is unlikely to
succeed: since the file format is unrecognized, all that can be done
is a simple
strings-like scan for ASCII words in the file. If
the file does not store words in an ASCII format, only garbage binary
content will be returned.
Note that unlabeled plain-text files - i.e. those not identified by
MIME type nor by file extension "
.txt" - will generally be
identified by a natural language scan (if running Texis 7.01 or
later), and properly passed as-is. This setting only applies to files
that fail that test, i.e. are unlikely to be plain text. Added in
