Hello,
I understand, that USB>Update USB option allows to update selected disks without altering others? If you have multiple items installed on USB (like antivirus, UBCD and Ubuntu) and you select for example only Ubuntu, and then use Update USB option- Ubuntu gets updated, but you still can boot to antivirus and UBCD as well?
What is the procedure for deleting items? Help is very brief on this subject: "SARDU on USB is incremental, later you can add other or manually delete old software. The menu creation is done by checking the USB support."
Regards,
