Hi Guix,

Simple questions

1.
when I want to open a file in KDE Desktop through Dolphin directly, I 
will be asked through which programme/package.

I have many packages installed in different profiles, so the package is 
not mentioned in the possible packages to open this file.

The only way to open a file is, to open the package from the profile 
beforehand,
and after that to open a file in pointing to this package.

This is a disadvantage to have packages installed in different profiles.

How can I bridge/bypass this?

2.
In MATE desktop in Caja and in KDE Dolphin it asks for the "user-defined 
command"
What is the command?
How can I find this package stored in the store, so that I can point to 
it in Dolphin, in the case I haven't opended the package from the 
profile beforehand?
(I don't know if that will help to open a file, if I haven't earlier 
opened this package from a profile)


thanks for help

Gottfried
