Java isn't deleting a file. I made sure it has permissions (full control to everyone, or 777 for you Unix-ers.) The System.out.println(currArchive.delete()) always returns false. Does anyone know why? I tried wrapping it with a try-catch security exception but it wasn't thrown. help? I made sure all my streams were closed, but it still returned false!
Here is my code:
addFile method of TarGzipManagerView.java

jfc.setMultiSelectionEnabled(true);
jfc.setAcceptAllFileFilterUsed(true);
jfc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
jfc.setDialogTitle("Choose files to add:");
int result = jfc.showOpenDialog(theframe);
if (result == JFileChooser.APPROVE_OPTION){
File[] addsf = jfc.getSelectedFiles();
totalNewFilesToAdd = new ArrayList<File>();
