HTML Preview functionality

Hello,

I want to build an html control that will be having two sides.

-         -  Left hand side will show all the files in atree view. The file can be of any type like: word, Text etc.

-          -Right Hand side will show the preview of the document selected in Tree view on the left hand side.

I didn’t find FileReader working in IE 10. On chrome it reads xml and text files only. Can you please confirm what types of file FileReader supports?

I want a way that At least should support Internet explorer.

Please help.

Thanks!
