This is an incredible problem to have with a brand new computer, not least a 24" iMac, but there we go. I brought a lot of files over from my PC and some of them are non-functional ... such as, for example, files with a "lnk" extension (which work as shortcuts on Windows). To tidy up the iMac I asked the finder to identify "lnk" files and it found 50. But there is NOTHING I can do to delete them once they are highlighted: not delete, not command-delete, not dragging them to trash, not going into menu and choosing the Trash option. They don't even delete individually. I have tried emptying my trash (which I didn't want to do) and restarting (which I didn't really want to do) - but nothing works. Can anyone help?
