The most straitforward way is to install emelFM2 which is a GUI file manager that can deal with the entire disk structure unlike the File Manager that comes with the N810 and only shows you files created with the GUI. On the CLI you can use "rm {file}" to remove a file. rmdir is for deleting empty folders. You can get emelFM2 at http://wardenclyffetower.com/MaemoFi...-rev29.all.deb
