LibreOffice doesn't show the ooxml format (docx, xslx, pptx) in fileopen dialog after selecting appropriate file type, though it can be opened. Step to reproduce: 1. Create .doc and .docx file, for the ease let them in the same folder 2. LibreOffice > File > Open 3. In "Files of Type:" dropdown, select "Text Documents" 4. Notice that there is .doc shown, but no .docx shown 5. Repeat step 1-4 with .xls/.xlsx/"Spreadsheets" and .ppt/.pptx/"Presentations", the same result occurs. Workaround: A. Select "All files (*.*)" or "Microsoft Word 2007 XML (*.docx; *.docm)" (or appropriate) OR B. Type file name into the dialog Tested and reproducible with [LibreOffice 3.3.3 OOO330m19 (Build:301) tag libreoffice-3.3.3.1] and [LibreOffice 3.4.2 OOO340m1 (Build:203)] on Windows XP. So I chose the earliest version per http://wiki.documentfoundation.org/BugReport_Details#Version
Confirmed. Same issue in LibreOffice 3.3.4.1 OOO330m19 (build 401) on MS Windows 7 and on Debian Wheezy.
Since all new unconfirmed bugs start in state UNCONFIRMED now and old unconfirmed bugs were moved to NEEDINFO with a explanatory comment, all bugs promoted above those bug states to NEW and later are automatically confirmed making the CONFIRMED whiteboard status redundant. Thus it will be removed.
I think I know how to fix it. A record for me & others: In filter/source/config/fragments/filters/, select the filter that you want to add, for example calc_MS_Excel_2007_XML.xcu. In there, we have <node oor:name="Calc MS Excel 2007 XML" oor:op="replace"> Copy oor:name, in this case "Calc MS Excel 2007 XML", and append it to a proper filter in officecfg/registry/data/org/openoffice/Office/UI.xcu After build/install, this file will be in path-to-install/share/registry/main.xcd. To test this after build, you can edit this file, then restart libo to see the result. Assigning to me, now the problem is: do we need to add all ooxml-related filter?
Oh well, just found bug 49724
