Unindexing in Photoshop refers to the process of removing an image or layer from the document’s index. The index is a hierarchical structure that stores information about the layers and their contents, enabling faster access and manipulation. Unindexing an image or layer makes it independent of the index, allowing for more efficient memory management and potentially improved performance.
Unindexing can be particularly useful when working with large or complex documents containing numerous layers. By unindexing layers that are not currently being edited, Photoshop can allocate memory more efficiently, resulting in a smoother and more responsive editing experience. Additionally, unindexing can help reduce file size, making it easier to share and archive Photoshop documents.
