In attempting to make a backup, SuperDuper reports a corrupted file which it will not copy and therefore will not complete the backup. I moved the file to the trash, but when I tried to empty the trash, I got a warning box saying that the file was in use. The file is this one: /System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/ Libraries/./libsuncmm.jnilib Is it better I don't trash this file? If I should not, what do I do about it? If it's okay to trash the file, how do I find out what process it belongs to so that I can get it out use? Since it is a system file, does this mean that's impossible? TIA Peter
