What number of file formats XnViewMP really support?

[wolalodosz]

Though http://www.xnview.com/en/xnviewmp/#formats says that XnViewMP can read and write WaveL, J Wavelet Image, Enhanced Compressed Wavelet and JBIG, I can't view .IWC/.WIC/.ECW/.JBG files. No thumbnails for these files in the file browser, no such formats in "Settings\Interface\Formats" ("Choose the formats which you use for saving"). Option "Show all graphic format" is enabled. Maybe I need to download some add-ons or something like that?
