Yes you can create specifically named folders in Contacts in eMC
You can import Contacts as comma separated values (.csv)
However, you cannot Export from Eudora direct to eMC or Import to eMC direct from Eudora.
Your best option is to install a FREE version of The Bat! then…
1./ From The Bat! you can Import direct from Eudora
2./ Export from The Bat! in .VCF format to your desktop
3./ Import in .VCF format from your desktop to eMC
I know it is a round about procedure but as far as I am aware UNLESS you can obtain an unadulterated copy of Aid4Mail (it MUST be ver 4.64) there is no alternative.
