I have just bought an Acer Iconia A200 tablet. In my profession I need to be able to carry a large number of files created in Microsoft Works 9 word processor. But I can't get the files to open when I transfer them from my PC to the tablet. I get a message that there are no supported files. I connect the tablet to my PC with a USB cable, open the tablet and the files on my PC and clip and paste the files to downloads on the tablet. How can I get the files to open on the tablet.
