Over the last two weeks I set up a brand new iMac running El Capitan for my wife. After transferring the photos and documents from her old iMac, we discovered that there were several documents that Pages would not open, giving a “cannot open that format” or words to that effect message. After discovering these were Microsoft Works files, I found a reference to Works Document Viewer on the Apple Support forums and checked it out in the App store. It sounded like exactly what we needed, so I bought it—can’t go wrong for $3.99! It was incredibly easy to use and after experimenting with the conversion of a single file to ensure it would open in Pages, I batch converted all the Works files, which the program stored immediately in the new folder I had created for them. The batch conversion process took about one second when everything was ready to go. Couldn’t have been easier. We really don’t have any other files to convert, but this program was certainly worth every penny to breath new life into these old family documents. I recommend it highly.
