Description Andras Timar 2012-08-15 10:46:46 UTC 
It would be nice, if Windows Explorer shell extension of LibreOffice could extract metadata from Flat ODF files, too.
Comment 1 Roman Eisele 2012-08-16 16:48:36 UTC 
I second this.
Comment 2 V Stuart Foote 2014-05-31 15:00:14 UTC 
So at some point still need to implement Windows Explorer shell metadata extraction, of Flat ODF formatted (e.g. non-zip archive) documents.

Commit http://cgit.freedesktop.org/libreoffice/core/commit/?id=68909d3d25da0fe350319dfc82ca5b8fe9f38dc8 as patch for bug 52078 removed shellex handling of Flat ODF on Windows. So at this point, only have the generic thumbnail by type--and no Windows Explorer readout of document metadata.

See, https://bugs.freedesktop.org/show_bug.cgi?id=52078#c25 suggesting issue remains from Windows shell handling of zip ODF--is at least exposing the metadata a good suggestion as an EasyHack?

And, more ambitious might be to also provide a thumbnail rendering to the Explorer shell?

The code that reads ODF files is in shell/source/win32/shlxthandler/ooofilt/ooofilt.cxx, with the actual parser in shell/source/win32/ooofilereader/.

My project team and I (team of 3) have started working on this bug as part of our software development practicum at The College of Charleston.

Comment 7 Buovjaga 2023-12-06 13:13:12 UTC 
The existing code pointers are nice, but could there be an explanation for easyhackers on how to test the Explorer integration with self-built LibreOffice?

You would need to have a normal installation of LibreOffice first. But then, you would be able to replace all instances of "C:\Program Files\LibreOffice\program\shlxthdl\shlxthdl.dll" in registry, with respective path to the self-built version.

There might be more details ... needs experimenting.
