Hello Dean, Which model do you have? I have the Olympus DS-55 and I have deleted files recorded on the unit through the USB connection to the PC with no problems. I don't use the DSS software and the recorder works just fine. If you accidentally deleted the voice files they're easily found on the CD so it's just a question of selecting the right language and copying them back to the recorder. Best wishes, Clive pallett ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
