Starting Preview without opening previous PostScript documents

Do you want to disable the App re-open the documents when you launch the App? So, you can go to "System Preferences" > "General" and enable the "close windows when quitting and app" option.

To amplify what Nelson said above, here are the full list of steps which worked for me on OSX 10.10.2:

Quit Preview if it’s running.

Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:

      Containers/com.apple.Preview

      Preferences/com.apple.Preview.LSSharedFileList.plist

      Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist

      Saved Application State/com.apple.Preview.savedState

Log out and log back in. Launch the application and test.

OSX 10.10

When you want to quit first close (hit the red circle) on all the windows/documents that the app has open. Then Quit the app.

I have several windows/documents (in textedit) that I leave open when I quit, so they will open when I reopen the app, it works with most OSX 10.10 apps. I use them as a sort of note pad, NOTE: if the system crashes you could loose the data if they have not been saved at some time.

You can do a Finder search for com.apple.preview and find the files you need to remove:

From Terminal, you can go to
~/Library/Saved\ Application\ State/com.apple.Preview.savedState/

There you can remove the window_*.data files that include your previously open file list.

You can also remove windows.plist and that gets rid of all of them.

This worked for a colleague: you can type alt/optcmdW when opening Preview, then quit an re-open.
