I've search everywhere and the most common one is c/users/user/AppData but thats all they give you doesn't tell you weather its ion Local, LocalLow or Roaming, ive checked in all 3 folders and cant find them, i want to delete half my save which is a fair few and its a pain in the ass to do it in game so if anyone could help that would be great

MyDocuments/MyGames/Dishonored

It's in C:\Program Files\Steam\userdata\[usernumber]\205100\

I found it in the remote folder. If you want an easier way to find Steam save locations, I recommend http://pcgamingwiki.com/wiki/Home

Hope that helps.
