A moment ago I got a question from a user who wanted to know what the differences where between two files (versions) in a document library which where uploaded.
I knew in Office there was a function to compare two documents but how to use it with SharePoint versions I never tried. Sometimes the answer is so close in front of you it turns invisible.
The trick is to just open the file from SharePoint in Edit mode. Word will open and under the review tab you find a button called compare. Just choose Specific version from the pull downmenu and a list with the versions inside SharePoint is being displayed. From here Word will take over and do the rest. Even if you choose to combine SharePoint will turn it in to a new version.
This function only works if versioning is enabled for that document library and is not available in Office Web Apps. You need the full Word application for this.
I had to shamelesly steal some images of the internet and make one with a Dutch version of Word, but all together it gives a nice image of the words descibed above 🙂
