The LMBS file extension identifies filter-related data associated with Adobe Photoshop for Mac, Adobe's image-editing software for Apple Macintosh computers.
The file contains data used by Photoshop's filter functionality. It belongs to the software's supporting resources and is not normally a standalone image, project, or document file.
An LMBS file is normally used internally by the compatible version of Adobe Photoshop for Mac rather than opened directly. If it came with a Photoshop installation or filter, keep it with the related software resources and use it with that software.
Double-clicking the file generally will not display its contents.
There is no practical standalone conversion method for an LMBS file. It contains filter resource data, not an image or document that can be exported to a common file format.
To preserve the filter, retain the original file and use it with a compatible version of Adobe Photoshop for Mac. Apply the filter in Photoshop and export the resulting image separately if needed.
