I'd got to thinking that it'd be nice to transfer multiple files from the queue at a time. Fortunately Chris is ahead of me on this one. If my case I'm transferring to one host so I did drilled into the Site Manager>pick-a-site>Advanced>Connections. On that window in the "Connection Types" box I selected the radio button for "Multiple for one host" and changed the "max connections:" setting to "3". Now I'm processing three files from the same queue in parallel. For me that keeps my aDSL connection fully utilized.
Now I'm curious, does this setting on a site in site manager also impact usage of that site when using the command line? It doesn't appear to based on the "status window" (To get the status window for command line transfers look for the CoreFTP icon in your sys tray. Right click it and select Status.) In the status window only one file is listed and it the transfer is nearly all my aDSL bandwidth can support. But I'm not sure it the command line only found one files to transfer.
