If you need to create a new product in your X-Cart store and know that you already have a similar one in your store catalog, you can create a new product by cloning the existing one.
To create a product by cloning:
On the product listing page of your store's Admin area (Catalog > Products), select the product(s) you want to clone.
Choose to clone the selected product(s) with the "Clone selected" tool.
When prompted, confirm your intention to clone the selected product(s).
The store will create an exact copy of the product selected at the previous step. Your online store will generate the name and SKU of the cloned product based on the original SKU with the addition of "-clone-N," where N is the clone number id. the rest of the info will be identical.
Edit the information of the clone product as you require.
Save the changes.
If you selected multiple products at Step 2, you would see the resulting clone products as a list on a separate page. You will be able to edit and save each of them separately. Note that you can access the page with your clone products at any time via the "Cloned products" page of your store Admin area (Catalog > Cloned products).
