I use packetnews but it don't give you too much. I also found like searchxdcc.com and more when I googled xdcc but which engine do you guys use? Post em up...

I never even tested a xdcc, as stated miljons of times on this forum mirc aren't a share apps.

Considering Packetnews is mostly for illegal downloads and most XDCC files are also illegal, you're not likely to get much help here. mIRC isn't for downloading illegal files, nor is it a good method for downloading anything. There are other programs out there that are better suited for downloading files of any sort.
