To free memory
The Purge command lets you free memory used by the Undo command, the History palette, 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 palette. Use
the Purge command when the amount of information in memory is so large that Photoshop’s performance is noticeably
affected.
