Don,

I've been wondering why attachments can not be transferred. Is there
some technical problem associated with them?

I believe it has something to do with their somewhat tortured history in Yahoo Groups. At various times:

1) They were stored along with the message and counted against your message storage quota. (circa 2003)

2) The quota for message content was eliminated, but attachments were no longer stored. They did pass through to members in individual emails (not digests).

3) The groups photo section got a major upgrade and its storage quota upped to 100 GB (while files remained at 100 MB). (Jan 2009)

4) The groups gained an option to store attachmentns on site, passing a link to the on-site copy in the emailed messages (individual and digest). If stored, attachments were were now stored in the same pool as Photos, counting against the same quota. Or the group could continue passing attachments through to to members on individual messages without storing them. (Feb 2009)

The bottom line is that Yahoo Groups, if your group is set to store them, keeps them in a separate pool of storage from the message content. If you've received a getmydata download from Yahoo you'll find that the mbox file(s) containing group messages have placeholders in them where the attachment(s) to a message should have been.

There is a separate folder named photos_and_attachments, reflecting their combined storage, but in few of my group downloads does that folder actually contain any attachments, even for those groups where I've had them set to store on site since the option first became available.

Your Mileage May Vary.

All that said, PG Offline seems to manage to get them, at least some of the time. Some of my groups' downloads have messages that have links to attachments, but there is no corresponding Attachments folder for that group and the links do nothing.

At least one of those groups (the original Y!GMF) has an abundance of both photos and message attachments stored on site. Why neither getmydata nor PG Offline downloaded any of either of them is a mystery.

Shal
