I'll try to describe you my config and to describe what can I do with formats I use in my work.I had named some. Let me try to lengthen the list, which can't be exhaustive
Archiver plugins installed (in their order in the list, because order of plugins is very important in FC XE)
-TotalObserver - could be dounloaded here http://wincmd.ru/download.php?id=totalobserver
associated extensions: totalobserver
-Total7Zip - could be found here viewtopic.php?f=6&t=6924#p22653
associated extensions: 7z.xz.bzip2.gzip.tar.wim.zip
-fcRar - internal FC plugin
associated extensions: rar
-fcZip - internal FC plugin
associated extensions: zip.jar.war
Viewer plugins installed:
-OOView - to view OpenOffice format in internal FC viewer (ODT, ODS, ODP, ODG, ODF, and many more, you can see list of all supported extensions in plugin), could be downloaded here http://totalcmd.net/download.php?id=OOSimpleViewer
-Office 2007 - to view MSOffice format in internal FC viewer (DOCX, PPTX, XLSX, PPSX), could be downloaded here http://totalcmd.net/download.php?id=office2007wlx_64
Now what can I do with described above formats
-With Enter key or doubleclick from mouse I can run any of Open/Libre Office or MS Office files as registered application.
-With Ctrl+PageDown I can open any of Open/Libre Office or MS Office files as archive (even old DOC, XLS, PPT, ... could be opened as archive). Archiver plugins give me ability to do that.
-With F3 key I can view content of any Open/Libre Office or MS Office files in internal viewer as plain text (old DOC, XLS, PPT, ... could NOT be viewed in internal viewer because I have no necessary plugin installed, but you can install ListDoc 1.2 plugin to view DOC files and Excellence 1.20 to view XLS files).
If I had plugins for all other formats, that you listed (EPUB, CAPX, MXL, CDR, ...), I can make the same with them, but I don't use that formats in my everyday work.
So you need to inspect your settings and install necessary plugins to make everything work fine.
Have a look at viewtopic.php?f=18&t=7075 to find plugins you need.
