You can select a folder to save an exported item in within the Export panel:
The Default destination is always in your iClone Custom content. In the case of a Prop this would be saved in the root of your Custom>Prop folder. If you wish to save the item somewhere else, a Sub-folder for example, then click on "Other" and browse for a target folder.
