I have a number of files that got copied to and HFS+ disk on my Mac somewhere along the line. They came from Windows 10. The files can't be deleted normally from the trash. I can move them out of the trash and then try using terminal to either delete them using rm -rf (which fails). I've tried to rename them too make them 'normal' but that fails too. For example: mv "._20090801-2555903 (2018_04_11 18_36_40 UTC).ldx" "20090801-2555903 (2018_04_11 18_36_40 UTC).ldx" does not work. Using sudo to rename or delete does not work. All I get is an 'operation not permitted' error. The files do not show up in finder, even when I have hidden files turned on. The files don't show in terminal with just 'ls', then only show with 'ls -a' Disk repair does nothing, file structures are fine. OSX simply refuses to let me delete them (given my poor skill level). How do I delete them?
