All Document Reader, File View

Couldn't even open a file without a popup notice saying "it's time for a ad". How can you think it's "cute" to do that before we try the app to see if it actually works and is what we're looking for. Your bloody ad's work fine, don't know about the app as your ad went longer that I spent looking for a file to open. Deleted it straight away. Gave 1 star rating because I had to leave something. If you like ad's this app is just for you. Ridiculous.
