plugin will copy converted files to the destination folder instead of creating links, if you choose to convert files. now converting files makes sense only for file formats unsupported by destination device (this can be set up in sync link device properties). i've removed the option to create links in any case (this option served to force creating links if conversion caused by embedding artworks only), because syncing time was the same with this option on and off. for now, adjust artwork settings in sync links device properties.
