Cannot delete icon services cache from trash.
Hi everyone, I have a 15" macbook 2014 running yosemite. I was having trouble with a download that was stuck on pause so I thought I would empty the cache for the mac store. I trashed a file named com.apple.iconservices.store. That was fine I rebooted and OS X recreated cache as normal. After that I am not able to delete folder from trash because it says the files inside the folder are in use. the files have names like this 1AEDA0FE-C8DB-52F8-3A88-57A134262EB1.isdata. I have managed to unlock the folder by changing the permission settings and I removed a file and changed its name thinking it wouldn't recognize the file. I still get an in use prompt even with a bogus name. Any suggestions? should I just ignore this file in the trash? seems like if it is going to be a problem I should just revert back to an older time machine since it has only been a week at this point. thanks.
MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10.2)
