Ok, so I'm trying to delete some old video folders that are taking up a lot of space on my hard drive, but whenever I try to move the items to the trash it tells me "The operation can’t be completed because you don’t have permission to access some of the items." I already tried to Verify and Repair permissions from Disk Utility, but it didn't work. I have the same problem trying to delete some Adobe folders from my Applications folder. I uninstalled all the Adobe Applications that I had on my hard drive using AppCleaner, so I'm not sure why those folders have stuck around. I'm still fairly new (I've only had my MacBook for 2 years) to the Mac OS and I didn't know what I could do to fix this. Thanks in advance for your help!
