In bryce in the presetsobjectsuser drawer there are temporary files left after you use bryce. They have .tmp at the end of the name. You can safely delete these. Dont delete the .obp files If you delete the temporary files you can save HUNDREDS OF MEGABYTES of disk space. Bryce makes these temporary files even if you import objects and dont save them as presets. --I hope this isn`t basic information that everyone knows already. :) --
