What if my DOC file gets more damaged after repair process?

This will not happen as Yodot DOC Repair is read only software which will not alter original file but instead gets information from it and create new and healthy DOC file. To check its capability, you can download demo version of the application. It is same as full version, but you cannot save repaired file in desired location. To save it in preferred location you should activate full version by spending few bucks.
