fatdan: so where are they stored now?
Shared objects, .sol files, and asset cache. I have my adobe settings manager set to 0 and 10.
Wise Jet Search is killer at finding and shredding these flash tracking, invasive cookies/files. Takes about 30 seconds and the are gone. Just type in assetcache, and click on the 1st thing that shows up (the top one), the click shred (if you can) or delete. Then type in macromedia, click on 1st thing again, click until you see Local Shared Objects, then shred or delete. Then click on the macromedia folder that's left (under shared objects folder in search box, you'll see it), then keep clicking until you .sol, and shred or delete that, too. That eliminates every trace from flash. You can do this while playing if you want.
I use ASC Pro and CCleaner Pro, and they don't go deep enough.
You can also use the search function on your computer, but Wise Jet Search is insanely fast.
