Thanks guys. Have tried everything suggested so far and STILL can't get it to work!

1. Copied address book to floppy

2. Opened this file on the same Pc and it has collected the complete list OK

3. Take the floppy to another Pc, and try to Import it, get message that 'An error had occurred during the Import Process.....etc'

4.Tried to open the file on the floppy in Windows Explorer and get message 'The specified file does not appear to be a valid Address Book file'

5. Checked Properties of the file on the floppy and find Type of File: Address Book File

So that's it, I know when I am beaten!
