About formats

TXT (Plain Text) is the most fundamental digital document format, storing unformatted text as a sequence of character codes with no embedded styling, layout instructions, or metadata beyond the characters themselves. The foundation of plain text computing traces to the ASCII standard published in 1963 by the American Standards Association (now ANSI), which defined 128 character codes including uppercase and lowercase Latin letters, digits, punctuation, and control characters. Modern plain text files typically use UTF-8 encoding, a variable-width Unicode scheme that encompasses virtually every writing system worldwide while maintaining backward compatibility with ASCII. Line endings vary by platform convention — LF on Unix/macOS, CR+LF on Windows — though most contemporary tools handle both transparently. One advantage is absolute universality — TXT files can be created, read, and edited on every computing device ever manufactured, from 1960s mainframes to modern smartphones, without any specialized software. The minimal overhead is another core strength: plain text carries zero formatting baggage, making TXT files ideal for configuration files, log output, data interchange, source code, scripts, and any context where content must be processed programmatically. Plain text serves as the substrate for structured formats like CSV, JSON, XML, YAML, and Markdown, and remains the input/output medium for virtually all command-line tools and programming environments. Despite decades of richer alternatives, TXT endures as the one truly universal document format.

MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.
