Convert pr to psd

What is the difference between .pr and .psd?

Description: The PR file type, associated with Sun Icon/Cursor, refers to a specific format used to store icons and cursor images on systems that supported Sun Microsystems' graphical environments. These files typically contain bitmap images designed for use as graphical user interface elements, such as icons for applications or interactive cursors for mouse pointers. The format is tailored to the needs of Sun's software and hardware platforms, which were prevalent in the 1980s and 1990s, particularly in academic, engineering, and enterprise environments. Despite its historical significance, the PR file format is less commonly used today, given the evolution of computing technology and graphical standards.; A PSD file is an image file created by Adobe Photoshop, a professional image-editing program often used to enhance digital photos and create web graphics. It is the native format used to save files in Photoshop. PSD files may include image layers, adjustment layers, layer masks, annotations, file information, keywords, and other Photoshop-specific elements. They are commonly created and shared among graphics professionals.
