There are service menus you can add to handle specific filetypes

/in/ KDE, code for Ark to open such files would be best.
The term "service menus" drew me toward an answer , however, after
realizing that the info found was for kde3/konquerer , then finding
kde4/konquerer, kde3/dolphin, kde3d3lphin, kde4dolphin differing paths,
and differing .desktop file contents required, I have exhausted my
patience. Eg: 
Let's say I create a file called tnefextract.desktop containing:
[Desktop Action tnefExtractToSubfolder]
Name=extract TNEF archive
and place that in:
along with two other .desktop files, and they seem to have the same
format as the above.
What else is required (on Fedora) to actually make the association work ?
