While aiming to make backup to an external USB hard drive, I created a Zip file so that filetypes would be preserved. Leaving it to get on with it, it eventually crashed the machine (Iyonix). After re-booting, DiscKnight showed the Hard Drive was still "good". Double-clicking on the Zip file resulted in an error message inviting me click on one of 3 buttons. You know: Continue or Quit or Describe. Clicking on Continue removed the hard drive from the Filer. After re-booting, the same happened, in succession, with the Quit and Describe buttons. Another re-boot. Menu->ZipFile->Count gave 2.1nn-something Gigabytes. Is that size the problem? Version 1.41 appears to be current. Regards. Frank. -- Frank Watkinson. email: <frank@xxxxxxxx> Using !Pluto 3.04c on Iyonix 5.10. Still RPC-SA (4.39 Adjust) for some things.
