Not sure if files written in MS Office 2007 are compatible? The truth is that they are with a bit of work on your part. If you are running an older version of a program and try to open the 2007 file, it will prompt you do download a conversion program. If you are online, follow all directions – including downloading other updates first. Your computer can then convert the 2007 file to something your computer can work with. Word of warning though, if the file contains features that became available in 2007, your converted file won’t have them.
