Unfortunately with this device the VN-2100PC it is not possible to rewind and overwrite any dictations that were done. Each time the record button is pressed and then the stop button is pressed it will create a new file. They may want to look for a DS-2300 or a DS-2400 recorder as these devices have the ability to rewind and allow you to dictate over previously recorded information in the same file. There is a button on these devices called "New" that allows you to stay within the same file until you press New to start the next audio file.

You can rewind and playback only. You can only record by creating a new file.

you can not do this with the Olympus ws-100, you need a dictation machine that has the editing function which allows you to easily insert, overwrite, partially erase files and continue on the same file, most of the digital dictation units have NEW FILE BUTTON , you will stay recording on the same file till you press new.
Look at Olympus DS-2300. Olympus DS-33300 or ds-4000.

you can rewind a tad and listen, but you can't overrecord, because a digital recorder writes audio information into a data file and saves it. you just can play it back again and record a new file. if you want to cut off a part of your recording, you have to edit the file in an audio editor. - as the olympus stores wma-files, you'll have to convert them into wav format first to edit them. i tried the 'switch' software successfully.
