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.

ICO is the icon file format for Microsoft Windows), introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.
