PutPlace only recognises changes that take place on your PC. Any additions or modifications are reflected by PutPlace in your stored online content. It doesn't work the other way around.
However, it’s still easy to access and use your online content. Just make sure to download what you have changed to your home computer and PutPlace will keep a current version of everything for you.
PutPlace can also keep copies of earlier versions of your data, so that you can backtrack easily if you need to in the future.
