PhotoShop Brush Delete Help.

I would like to delete alot of photoshop brushes I downloaded without resetting the brushes to default. Is there a way where I can delete more then 1 brush at a time. I’m using Photoshop CS3 Extended.
Thank you.
Answer #1
go here
C>program files>adobe>photoshop cs3>presets>brushes
then delete from there
Answer #2
But that would delete all the brushes in that pack.
Answer #3
on the brushes tool. Select brushes and press Append than include all the brushes. Select the brushes u want to delete and press Del to delete. Than Savenew brush set like “new brushes.” then go to X>program files>adobe>photoshop cs3>presets>brushes Select the other brushes set and delete. use new brushes to use favourite brushes.
