I extracted my sounds and cursors from the Travel theme a month ago
using Find and my old Win98 disk. I believe what I did was to point it
toward the D drive, narrowed the search to the win98 cabs section, and
put travel* in the box, with the advanced option checked to search
subfolders. The default for XP seems to be that files are sought
inside compressed files. If you only want sounds, then your search
would be for jungle*.wav.
It's somewhat fiddly but do-able.
