I have a question about filters and wildcards:

I only want to transfer files ending in '_20.jpg', '_21.jpg' ....30/31/34....
and _34_d.jpg;_35_d.jpg.........

how do I set the filter for this?

How much drive space is required to monitor and record from 3 IP cameras?

I have 300gb available on my external drive and it tells me there is not enough space and recording will stop. I am not sure why this is happening it was working fine for a month. The files that were recorded earlier are only around 20MB.
