sxc is the old extension for StarOffice Calc Spreadsheet, I still have some sxc documents from 2006/7.
I've just copied these to two other destops, openSUSE 13.2 ands a vanilla openSUSE 42.1. Open Dolphin, locate document, double-click and LibreOffice opens the document. Any chance your document isn't really SXC compatible? If you run "unzip -l" on it, you ought to get something like this:
unzip -l document.sxc Archive: Documents/document.sxc Length Date Time Name -------- ---- ---- ---- 28 05-24-06 15:47 mimetype 0 05-24-06 15:47 Configurations2/statusbar/ ...
$ unzip -l xorgLayoutConfigs1602.sxc Archive: xorgLayoutConfigs1602.sxc Length Date Time Name --------- ---------- ----- ---- 0 2016-02-29 02:33 mimetype 319899 2016-02-29 02:33 content.xml 721 2016-02-29 02:33 meta.xml 2413 2016-02-29 02:33 styles.xml 1626 2016-02-29 02:33 settings.xml 703 2016-02-29 02:33 META-INF/manifest.xml --------- ------- 325362 6 files So, my problem here was that I chose a bad non-native file format for saving my work, because KOffice 3 is unable to save(as) an .sxc file that it can itself read. -- "The wise are known for their understanding, and pleasant words are persuasive."
