How annoying I am trying up create a back up copy of my home directory, my mac tells me some destination file is locked so it cannot be overwritten. I do not know how it got locked (whole bunch of files are locked), but whatever I try fails (when I try to change the ownership it asks for the admin password, I give it, then it says you do not have privileges to do that!). I do not have the privileges to change them. Very strange, I created those files by copying from my mac to an external HD. Any ideas how I can fix this? I cannot even delete the files. When I deleted them it put them all in the trash. But now I cannot empty trash because the files are locked! How can I get rid of those in my trash?
