Where is the screenshot property list now located in Mavericks? Previously, the screenshot property list could be found at:

~/Library/Preferences/com.apple.screencapture.plist

In Mavericks, this file no longer exists. In the past, I used to be able to manipulate the location and image type of screenshots using the .plist mentioned above. Where are these values now stored? Do I now need to create the plist in order to manipulate these variables, IE:

defaults write com.apple.screencapture location ~/folder/of/my/choice


To be sure this was not an issue with my user account, I created a new admin. account and tested.
Looking at my MBA with 10.9.2 it is still in the


  User/myname/Library/Preferences/com.apple.screencapture.plist


As it turns out, the .plist will only exist (be created) if you modify the screencapture settings, like location to save and others.
