delete-by-moving-to-trash is a variable defined in ‘src/fileio.c’. Its value is nil Specifies whether to use the system’s trash can. When non-nil, certain file deletion commands use the function ‘move-file-to-trash’ instead of deleting files outright. This includes interactive calls to ‘delete-file’ and ‘delete-directory’ and the Dired deletion commands. This variable was introduced, or its default value was changed, in version 23.1 of Emacs. You can customize this variable. --- If this option doesn't work for you, you should report a bug.
