"Open With" context menu full of copies

I'm a new and very happy user of SuperDuper! but have discovered one thing I'd like to try and fix. [I'm pretty sure that any software that backs up by creating a bootable clone will suffer from this, so apologies for posting here]

Soon after I started using SD I found that if I right clicked on a movie file in the Finder I would get multiple entries for QuickTime, RealPlayer etc. so it seems that finder is scanning all mounted disks to populate this menu.

Worse than that, it seems to add new entries when a disk name changes (I played about a bit to get a partitioning scheme I was happy with) without forgetting old ones so I'm now up to around 6 copies of QuickTime appearing in the menu.

I have disabled Spotlight indexing on my clone volumes but would like a way to prevent Finder from scanning my external FireWire drives for applications - is this possible?

Once they're found, it's a pain to unfind them, but you can do so by clearing the LaunchServices cache. To do so, check this article from Mac OSX Hints.

Let me know if that helps.

BJJ, If you are not comfortable working in Terminal, you can easily Rebuild Launch Services with Cocktail (and other utilities such as OnyX). These utilities automate the process- just click on the Rebuild Launch Services Database icon and voila!

Brilliant. I just ran the command in the hints article and relaunched finder - straight back to just one of each application.

Thanks also for the Cocktail/OnyX tip, I played with one of these in the past (can't remember which) but got fed up with it telling me to restart after every operation. I may have to have a second look and see what other goodies are tucked away.

Great. Glad that worked for you!
