Data Feeds

Can anybody help me?

I am trying to get an understanding of data feeds.

Is there anyway for cs-cart to update inventory from a vendor with a data feed file?

How can i automatically update inventory with just a click of a button?

Please let me know if anyone have any ideas.



I can not access the datafeed from my site it says


You don’t have permission to access /var/exim/google_general_04072010.csv on this server.

Could you help me?
