What are the options for managing data in Stock Sync when using FTP?

When using an FTP connection in Stock Sync, data handling depends on the feed type you configure. Stock Sync does not automatically perform an upsert unless you set it up explicitly. You must choose the intended behavior through one of the following options:

1. Update existing products only: Stock Sync updates products already in your store based on a unique identifier such as SKU. Items that exist in the FTP file but not in your store are ignored.

2. Add new products only: Stock Sync imports new products found in the FTP file but skips any products already present in your store.

3. Upsert (Add + Update): This requires creating two separate feeds using the same FTP source—one feed configured to update existing products and another feed dedicated to adding new products. This combination allows Stock Sync to update current listings and insert new ones when necessary.
