Sunnysoft InterWrite Pro is localization software for Windows Mobile and Windows CE. It allows a device's system language to be adapted for languages such as Czech, Russian, Hungarian, and Norwegian.
The .xht file stores various data used internally by InterWrite Pro. It is part of the software's data rather than a standalone document intended for editing by the user.
This is a legacy format associated with Windows Mobile and Windows CE. Its contents may not be useful outside the InterWrite Pro installation or the device for which they were created.
Use the related Sunnysoft InterWrite Pro installation on a compatible Windows Mobile or Windows CE device. The software uses the file internally rather than opening it as a standalone document.
There is no standard standalone conversion for a Sunnysoft InterWrite file. Because the file contains internal InterWrite Pro data, keep it with the related installation or device rather than trying to convert it with a general file converter.
