Photoshop Document
The industry standard for digital image editing.
PSD (Photoshop Document) is the proprietary file format of Adobe Photoshop. It is the de facto standard in the digital art, photography, and graphic design industries. Unlike final output formats (JPG, PNG), a PSD is a working file that preserves the editor's state: independent layers, editable text, masks, blend modes, filters, and paths.
A PSD file is divided into five major parts: File Header, Color Mode Data, Image Resources (metadata like paths, guides), Layer and Mask Information (the bulk of the data), and Image Data (a flattened backward-compatible preview). This structure allows Photoshop to save complex non-destructive editing states.
Created by Thomas Knoll in 1988 for the original version of Photoshop. It has evolved with every version of the software, adding support for new features (vectors in v6, smart objects in CS2) while maintaining remarkable backward compatibility.
Icon File
A generic, often ambiguous extension for icon resources.
The `.icon` file extension is a generic identifier for icon images. Unlike the strictly defined `.ico` (Windows Icon), `.icon` is often used in Unix/Linux environments or by tools like ImageMagick as a catch-all alias for various icon formats (including Sun Icon, XBM, or simply renamed ICO files). It is not a standardized format itself but a convention for naming icon resources.
The internal structure of an `.icon` file depends entirely on what created it. It might be a standard Microsoft ICO container with multiple sizes and color depths. It might be a persistent X11 bitmap (XPM). Or it might be a Sun Raster file used for icons on Solaris systems. Because of this ambiguity, it requires a robust viewer that detects format by 'magic bytes' rather than extension.
In the early days of GUI desktops (SunOS, IRIX, early X11), there wasn't a single unified icon standard like Windows .ico. The `.icon` extension served as a descriptive label for files intended to be used as desktop icons, regardless of their underlying binary format.
