About formats

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.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
