hi
i want to upload my files to others host (download host) not cpanel by using k2 and sell them by using k2store
can you help me?

K2's media are stored on the /media/k2 folder. I do not know how k2store handles digital files.

You can ask your hosting provider if he can decouple these folders from your current setup. Alternatively you can look for an extension that offers this functionality.
