The GG file type is associated with Koala Paint, a graphics program specifically designed for use on early home computers. It represents a compressed format used to store images created or edited within the Koala Paint software. This format allows for efficient storage by reducing the file size, making it easier to manage and share graphical data on systems with limited storage capacity. The GG extension is primarily recognized and used by vintage computing enthusiasts who engage in the preservation or emulation of classic computer systems and their software.
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.
