You no longer have to wait for the progress bar to creep across your screen when saving large files because Photoshop CS6’s Background Save feature can save files in the background while you keep working on other projects.
Auto Save, another new feature of Photoshop Cs6, can help recover your file if your computer crashes before you’ve had a chance to save. To select the time interval for automatically saving your files, select Preferences > File Handling and choose from every 5, 10, 15, 30, or 60 minutes.
Both of these features are on by default. To disable either of these options choose Preferences > File Handling and uncheck Save in Background and/or Automatically Save Recovery Information.
