Thanks for your response flhthemi.  I am using Kodi with the Aeon Nox Silvio skin to play back my Plex library.  I am using the addon Composite to access my Plex and when I long press or hit "C" for the context menu I get a range of options but nothing like what your examples are showing me.  The option to Edit titles, delete files etc are not available.  I get a whole string of options such as Refresh Library, Mark as watched, Play Transcoded, Mark as unwatched, Add to Playlist, Information, and many more but nothing about deleting a file.  It is possible a "Composite" addon problem so I may head to their forum and post my hassle there.  Thanks ..... unless someone else is using Composite with this skin and has worked out how to delete files.

I am getting ready for the movie to Kodi Matrix.  I have my setup working well using Composite with my Kodi 18.9 and I have previously used the highly configurable Xonfluence skin. 

However it doesn't seem likely Xonfluence will be upgraded to work with the new Kodi.  So I am trying the Aeon Nox Silvio skin which I have set up on Kodi 18.9 with Composite working fine ... except for the context menu to show to delete a file from my Plex.  I have allowed the option to show hidden files and to allow deleting of files in Kodi. In Aeon Nox Silvio I can bring up the context menu but the option to delete a file isn't available despite deleting of files being enabled as I can when using Xonfluence.  

Has anyone got deleting of files working in Composite and uses the Aeon Nox Silvio skin?  I have set up the Plex Kodi addon on the same version of Kodi and the Aeon Nox Silvio skin, signed in etc and can delete files from the Plex Addon easily via the context menu.

I've ensured I have logged into my Plex Account via Composite, I have set the Server (all via Composite "Settings").  I have restarted Kodi and gone to a file and 'long pressed' to get the Context Menu and I get Play Transcoded, Mark as watched, Mark as unwatched, Add to playlist, Audio, Subtitles, Update Library, Refresh, Play, Information, Mark as unwatched and Add to favourites.  But there isn't the option to Delete.  

It's as if I have signed into Plex via Composite but it isn't recognizing me as the Server Owner and therefore able delete files.  Note this happens with the skin Aeon Nox Silvio.  The delete option in Composite works fine if I'm using the Xonfluence skin.  The problem only occurs when using Aeon Nox Silvio.

All my own fault, In Composite I went to Settings, Look and Feel and there, way down at the foot of the menu was "Show delete in the context menu" and then hit Save.  All sorted!
