10.6.8 can't read files correctly after updating to High Sierra (APFS) - Eudora

[rng]

The Eudora Settings file is 92 k in High Sierra. The Eudora Settings file is 0 k as seen from MacOSX 10.6.8 via Parallels Shared Folders or when copying from High Sierra to 10.6.8 via the desktop. I'm running some old programs and, most importantly, Eudora in 10.6.8 to retrieve old e-mails.
