Current version of eOffice cannot read native files from your SD. You need to use eFile desktop to convert them prior to placing to the BB.
I guess I don't see the point of the app, then. If I'm at a place where I need to open a document on my phone, it usually means that I'm not near a computer. So having a program on my BB that ALSO requires document conversion on a computer has very little value to me. Hell, if that's the case, I could just as easily convert the documents to jpgs and not pay anyone anything. Also, I was ready to pull the trigger on MasterDocs and your service department dropped the ball. Waiting on hold for 30min for a supposedly 24x7 support department doesn't inspire confidence in your company.
John, I just bought Beamberry. It's not perfect, but at least it does what I want and is usable. No conversion required.
