Remove assets from Asset library
You can remove assets you no longer need from Asset library. When you remove an asset, it's only removed from Asset library. The asset won't be removed from:
- Projects it's used in
- Reports for ads it's serving in
- Other ad platforms it's been exported to
If you remove assets by mistake, you'll have 15 seconds to undo the removal and restore the asset. If you choose not to restore it, you can upload the asset again.
You can remove assets from either cards or table view, or while you're previewing it.
Note: Currently, you can't remove folders. This feature will be added in the coming months.
