archive-view should support iWork and Office files as special case of ".zip"

[AndreasTusche]

Several files are actually just zip archives and can easily be opened by archive-view when adding the .zip file-extension. Well, instead of doing that, may I suggest to support those files directly as a special case of zip archives and allow following extensions as well. I saw the #33 and #34 but you may have over-estimated the work to do, there is nothing more to do because the archive-view already has it all.

• .keynote Apple iWork Keynote file (Presentations)
• .numbers Apple iWork Numbers file (Spreadsheets)
• .pages Apple iWork Pages file (Text processing)
• .pptx MS Powerpoint file (Presentations)
• .xlsx MS Excel file (Spreadsheets)
• .docx MS Word file (Text processing)

By the way there are some more zip archives out there, you may decide to support them as well. The first bytes are "PK.." (hex: 50 4B 03 04), see also the table of file signatures (aka "magic numbers").

Thanks for taking this in consideration.

I would add OpenDocument Format (ODF) files to the list. They are also just zipped XML files.

• .odt, .ott, and .odm for word processing (text) documents
• .ods for spreadsheets
• .odp for presentations
• .odg for graphics
• .odf for formulae, mathematical equations
