You can locate a previously
rendered item or check the destination of a queued render item by
expanding the Output Module group in the Render Queue panel and clicking
the underlined file path, or by right-clicking (Windows) or Control-clicking (Mac
OS) the Output Module heading.
Specify the filename and location for a single render item
Change the destination for multiple queued render items
Create and use a custom file naming template
To make a file naming template the default template,
hold down Ctrl (Windows) or Command (Mac OS) as you choose the template
from the Output To menu.
Name output files automaticallyThe Use Default File Name And Folder preference ensures that all compositions added to the render queue are automatically assigned a unique output filename (except for files created by saving RAM previews, which still use the composition name). When this option is selected, each render item is assigned the same folder name as the previous render item until you change the path. If a composition is rendered more than once, After Effects adds a number to the filename (for example, composition_name_1).
