[sv-discuss] [DISCUSS] ODF file formats vs Zip

When working with big files, in my case spreadsheets, but possibly
other types of office files, saving the file will in some cases take a
lot of time. This is particularly annoying when auto-saving is
enabled. As I understand it, an ODF is a couple of files, most of them
XML files, brought together in a single file, then compressed to the
zip format.

Does the ODF standard specify the compression ratio? If not, it would
be convenient if the user could specify that. For example, if I prefer
saving to be as fast as possible, I could specify no compression at
all, just bring the files together in a tar-ball (if that's allowed)
or as an uncompressed zip.

I don't know how much of the required time to save a file is used for
compression, but I imagine that there is room for speed enhancements
here.

If this is not the way to go, maybe the extension could change as
well, indicating this is another file format, although conversion to
and from ODF should be very straight forward…

Thoughts about this?

Personally I just thing that something must be done about the auto-save speed.

And also, when opening a spreadsheet, ”adapting row heights”, what is
that? Is that really necessary? Shouldn't row heights already be
specified in the ODF file? It's maybe not the same subject, but in a
way it is about time consuming saving and opening of different kinds
of ODF files…

Hoppsan… insåg inte att jag skickade detta till den svenska diskussionslistan…
Trodde jag skickade till den globala listan för
LibreOffice-diskussioner och Apache OpenOffice-användare (det verkar
inte som att Apache OpenOffice har någon diskussionslista), men det
var visst bara den sista som fick rätt adress.

Hoppas ingen blev alltför förvirrad av detta.



Med vänlig hälsning
