Use Assets : Drag and Drop : Copying Categories and Associated Assets
   
Copying Categories and Associated Assets
Categories can be dragged and dropped – along with the assets associated with each category – into the Windows Explorer or the OS X Finder. When you drop the categories, Cumulus creates a folder with the same name as the category and copies the assets to that folder. If the category contains subcategories, subfolders will be created and the assets assigned to these subcategories are copied to the corresponding subfolders.
This option may be handy for collecting production files for output (assuming the files all have at least one common category, such as project name).
To copy categories and associated assets:
 
1. Select one or more categories that you want to copy along with the associated asset files.
2. Drag and drop the selected categories into the target application.
NOTE: If you use this way of copying assets, any associated metadata files (e.g. TAG files) will not be copied even if the corresponding metadata modules are activated.
A folder named as the category is created containing the asset assigned.
You also have the option of copying only the asset files associated with selected categories (see “Copy Assets Assigned to Category To” ).
