Are Writelog, Dxbase, and AR-Cluster compatible with NTFS? Microsoft recommends NTFS with XP. The backup program included on the XP Home CDROM will only work with NTFS drives >4 Gb. I certainly don't want to do it if these programs won't run. Others of interest include DX Telnet, Geoclock, MMTTY, and probably others. Better to ask first than regret later. (This is a new approach for me.) Thanks, Jim N7US
