Application Interface

create .desktop files

.desktop files put applications in the desktop menu. The files are placed in /usr/share/applications and ~/.local/share/applications.

If the path to executable contains spaces it needs to be put in double quotes. Single quotes do not work.

A nice tool to edit and create such files is MenuLibre:

Install via sudo apt-get install menulibre afterwards just launch it from command line menulibre and create e new entry for menulibre itself so it will appear in Applauncher.

default application

The MimeType field in the .desktop file tells the os which files the application can handle. The default application for a MimeType are configured in ~/.config/mimeapps.list

vs code issue (super+e)

Vs code opens when you press super+e instead of the file browser. To resolve the issue add inode/directory = dde-file-manager.desktop;code.desktop; to ~/.config/mimeapps.list.
