after removing something(i guess it was konqueror) i've lost the create "new folder" item in the context menu in dolphin. should i reinstall konqueror or is it not connected with konqueror?

Do you have a 'Directory.desktop' file in '/usr/share/templates'?
If not create one and type these lines in it:

Code: Select all

[Desktop Entry]
Name=Folder...
Type=Link
URL=.source/emptydir
Icon=folder

Let us know if it works!
