I have some like that too, as i keep opening them up to see what they are, i get used to knowing what they are, LOL... I would make another folder in your presets (Usually - C:Program FilesDAZBryce 5.5PresetsObjects?? ) and place them in there then delete them from your main Misc category when Bryce is opened.... Something like: Buildings or terrains. so you would end up with: C:Program FilesDAZBryce 5.5PresetsObjectsBuildings. Marc :)
Smile, your dead a long time :)
