Is there anyway to open word and excel documents, for free, that you havent recieved through an email, meaning you've directly uploaded to your computer?

Using DocumentsToGo, yes. Included in OS 4.5.

I have 4.5. Doesnt say anything about DocumentsToGo...
Does it cost any money at all...like data charges or anything they may manage to charge me for?
I dont have a data plan

You probably did not load DTG when you loaded your OS 4.5, you might have not checked the app loader box for it to be included.

Ok installed with no issues.
so now im wondering...does it cost to use? Like i know some programs link up to the internet so you'll get charges for using them

There is no cost to use. However, there is an update to add Sheet To Go. The update is 2.2MB and needs to be downloaded OTA so there would be a charge for that (if you're on Robbers.)

haha i like that :P (Robbers)
so im gonna guess this is like a trial program right?

DTG is free to use in the limited edition you loaded.

It is not trial, it is simply limited to viewing, editing and saving documents.

And the version with the OS doesn't include Sheet To Go (Excel.)

Oh beauty great to have and thanks so much or all your help ;)
