Working on the 869 post ...
'LittleMissMe' said that Winrar gave up with 'no recovery record
found'. Don't yet know what version of Winrar she's using,
But with 3.71 it sailed through and fixed it.

Is there a way to get the properties of a .rar archive that shows
things like whether or not it has a recovery record, built 'solid' and
other attributes?

Pretty tricky for most! In this case, when winrar recovers it, it
states that the archive header is corrupt.
Interestingly, if I tell it to treat the archive as 'solid' it creates
one folder. If I say not to, it creates the contents as a folder
within a folder. The source of BlueRopes problem may be that his/her
version of Winrar doesn't handle nested folders well.

Agree.

I agree. There are enough Outlook Express and Mozilla based
newsreaders being used that yEnc posting generally hurts more than it
helps. OTOH, many European users pay by the byte so it saves them a
few bits here and there.

Quite a bit, it would seem!
