About formats

SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.
Initial release: August 2010
PSD (Photoshop Document) is the native file format of Adobe Photoshop, the industry-standard raster image editor first released on February 19, 1990. PSD files preserve the complete editing state of a Photoshop project: all layers (raster, text, adjustment, shape, and smart object layers) with their positions, blending modes, opacity, and layer effects; layer masks and vector masks; alpha channels; spot color channels; paths; guides; slices; and the full undo history. The format supports images up to 30,000 x 30,000 pixels (PSB, the large document format, extends this to 300,000 x 300,000) in color modes including RGB, CMYK, Lab, Grayscale, Indexed, Duotone, and Multichannel, at 1, 8, 16, or 32 bits per channel. PSD files use a combination of RLE compression for individual layer data and store composite (flattened) preview images for quick display by applications that cannot parse the full layer structure. The format has become a de facto standard for professional creative workflows far beyond Photoshop itself — photographers, graphic designers, web developers, and video post-production artists exchange PSD files as the working format that preserves creative flexibility. One advantage is the non-destructive editing model: PSD preserves every layer, mask, adjustment, and effect as independently editable elements, allowing creative decisions to be revised at any point without starting over. The format's role as the interchange standard for the creative industry provides another core strength — PSD files can be opened by Adobe Illustrator, InDesign, After Effects, Premiere Pro, as well as Affinity Photo, GIMP, Sketch, Figma, and Photopea, making it the lingua franca of visual design.
