If you have a separate user writable drive mounted, you may have encountered the same problem I had.
If your DE cannot create ``.Trash-$uid``, most DEs will not delete files to the trash at all and KDE will copy deleted files to your home partition.
I find both behaviors frustrating.

The solution is rather simple: look at the spec__ and create the trash directory manually.

.. __: https://specifications.freedesktop.org/trash-spec/trashspec-1.0.html

.. code-block:: bash

    # for example, your drive is mounted to /media/external
    # go to the drive root
    cd /media/external

    # create root owned .Trash
    sudo mkdir .Trash

    # make it world writable with a sticky bit
    sudo chmod 1777 .Trash

.. note:: Sticky bit is used for retaining control over your files in a publicly writable directory.
   Only the owner of the file can delete or rename it even if other users have write permission in the parent directory.
   This is a typical permission for ``/tmp``. `Read more`__

Now delete some file from that partition and check that is lands to ``.Trash/$uid/files``.
Your trash directory now works properly.
