Specify history and cache settings
❖
In Performance preferences, do any of the following:
•
To specify how many states the History panel displays by default, click the triangle on the History States menu and 
drag the slider.
•
To specify the cache level Photoshop uses, drag the Cache Level slider. You must restart Photoshop to have the 
cache settings take effect.
Free memory
The Purge command lets you free memory used by the Undo command, the History panel, or the clipboard.
❖
Choose Edit > Purge, and choose the item type or buffer you want to clear. If it is already empty, the item type or 
buffer is dimmed. 
Note: The Purge command permanently clears from memory the operation stored by the command or buffer; Purge 
cannot be undone. For example, choosing Edit > Purge
> Histories deletes all history states from the History panel. Use
the Purge command when the amount of information in memory is so large that Photoshop performance is noticeably 
affected.
