Mozilla attachments

[Tim <helycos@lycos.co.uk>]

I don't know how to view attachments from mozilla that are labelled 
'Part 1.2' and are of significant size eg 300KB.  I know of one to be 
photographic images.  If I try to open using /usr/bin/mozilla, it is 
unable, describing it as a binary executable.  I don't know what 
software was used to create these files, but I know they were from 
within windoze

Does anyone have any suggestions for me?

TIA, Tim
