Finder is taking forever to move, rename, etc. files, especially when moving to the trash or emptying the trash.

Here is a video

It takes 80-95% of my CPU and spins 13 threads to think about it for a few minutes: enter image description here enter image description here

What happens if you move the folder elsewhere in the filesystem instead of moving the files to the Trash, does it also need a long time? Does the folder reside on a external hard drive? How full is the hard drive where the folder is located? – jaume Dec 20 '12 at 9:28
Sometimes yes. No externals connected. 12GB remaining. – Kirk Strobeck Dec 20 '12 at 11:00
I don't understand the disconnect between the % CPU column data and the data at the bottom of the window, both numbers and graph. – JoshP Dec 20 '12 at 15:31
How old is the system you are working with? Was it a fresh 10.8 install or have you updated your OS for years? I'm thinking directory data corruption. – myhd Dec 21 '12 at 0:19

So, I took it to the Apple store, they weren't really any help. I held down option and reinstalled the OS in-place and that worked! Finally I can use Finder again .. whew! Let me know if this helped you.

Great if it worked for you. I assume manually clearing out the trash via Terminal (rm -rf ~/.Trash) wasn't helpful? – patrix Dec 24 '12 at 8:47
I'm not sure .. I never tried it. I went with the advice from the Apple Store – Kirk Strobeck Dec 28 '12 at 3:39
