| Hello,
| 
| some days ago i use internal updater of foxit reader. This is a
| proprietary PDF reader, but at least there exist ports of this tool for
| Linux and windows. Furthermore it is an alternative to all present
| Acrobat Reader and i like to have the same look-and-feeling on my
| different systems. The update process stores files on windows system
| in directories under "%APPDATA%\Foxit Software\Addon\Foxit
| Reader\Install". The file name extension is 'fzip'. This is now
| expressed by additional magic line
|  !:ext	fzip
| The purpose of these files is described in knowledge base of foxit
| software. So add that URL as remark line like
|  # https://help.foxitsoftware.com/kb/install-fzip-file.php
| When i run run file command version 5.35 on the Foxit add-on/updates
| files are described as "data".
| 
| The File identifying utility TrID ( See
| http://mark0.net/soft-trid-e.html) identifies such FZIP-files correctly
| as "Foxit Reader Add-on" by definition fzip.trid.xml found in trid
| database package triddefs_xml.7z. So i add that url as reference by
| comment line like
|  # reference:	http://mark0.net/download/triddefs_xml.7z/
|  #		defs\f\fzip.trid.xml
| The trid pattern expressed as magic line looks like
|  0	ubequad	0x2506781901010000	Foxit add-on/update
| The phrase "fzip" implies something like abbreviation for "foxit zip",
| but such files are compressed with an method, i do not know and no
| "PK" zip magic is found in such files. So mentioned this fact as note.
| Only readable strings at the end of files looks like "Update.exe"
| "setup.xml". So this seems to be a kind of auto executable SFX. So i add
| magic lines inside Magdir/archive after last zip alike pattern. That was
| "RZIP". And mime type is expressed by user defined typ via line
|  !:mime	application/x-fzip
| 
| After applying the above mentioned modifications by patch
| file-5.35-archive-fzip.diff then all inspected examples are now
| described like:
| 
| fileopen_plugin_reader_7.1.0.106_10.fzip: Foxit add-on/update
| firefox_plugin_reader_2.2.5.1013_3.fzip:  Foxit add-on/update
| fpdfcjk_reader_2.3.0.312_2.fzip:          Foxit add-on/update
| OCR_Lang_Dutch_1.7.0.505.fzip:            Foxit add-on/update
| pdfa_Phantom_2.4.0.411_2.fzip:            Foxit add-on/update
| Reader_9.0.0.29935.fzip:                  Foxit add-on/update
| Reader_ML_9.4.0.16811.fzip:               Foxit add-on/update
| Reader_ML_9.4.1.16828.fzip:               Foxit add-on/update
| UpdatePluginsReader_9.2.0.9182.fzip:      Foxit add-on/update
| UpdatePluginsReader_9.4.0.16807.fzip:     Foxit add-on/update
| 
| I hope my diff file can be applied in future version of file utility.

Thanks! Added.
