# Files

SellStack allows administrators to attach not only images (see media section) but also additional files to products. This feature is useful for providing customers with supplementary materials. Administrators can upload and attach files to products using the File upload form available in the SellStack Admin panel. Currently, the system supports uploading files in PDF and ZIP formats. When uploading, you can optionally specify a display name for the file. If a display name is not provided, the file will appear under its original filename.

Uploaded files appear under the Marketing Materials tab on the product detail page in the SellStack Shop. Customers can download the files by clicking on the file links.

Note: File display is currently supported only by certain SellStack themes. If the Marketing Materials section does not appear in your storefront, your active theme does not include this feature.
