# Copy Comp

## Description

Copy Comp duplicates a composition and its entire hierarchy. Cloned expressions are automatically updated to point to the new copies instead of the originals.

## Setup

1. Select a composition in the Project panel
2. Open the Copy Comp tool
3. Configure the options below
4. Click Run Copy Comp

### Options

**Prefix**\
Text added before the original composition name. Leave empty for no prefix.

**Suffix**\
Text added after the original composition name. Defaults to `_copy`.

**Folder Name**\
Name of the project folder where the duplicated compositions will be placed. Keeps your project panel organized by grouping all cloned comps together.

**Updated cloned expressions**\
When enabled, expressions in the duplicated compositions are rewritten to reference the new cloned layers and comps instead of the originals. Turn this off if you want the cloned comp's expressions to continue pointing to the source.

**Open top-level cloned Comp**\
When enabled, the newly created top-level composition opens in the Timeline and Composition panels after duplication.
