hi all
i get work emails with PDF or EXC documents attached, but they wont open and can't view or save or modify if needed. i downloaded the kingsoft office but can see to find a way to use it to open these documents.
thanks for all the help.

For the .pdf file format download and install Adobe Reader from the Google Play Store. .pdf is an Adobe file format.

What is the type of program that uses .exc?
