EPOC AIF

EPOC Application Information File (AIF, or Symbian AIF) is a format used on EPOC/Symbian operating systems to store an application's icon and caption. Apparently, it is sometimes used as just an icon format, without an associated application.

Format
The images use the same internal data structure (sometimes called "Paint Data Section") as EPOC MBM and EPOC Sketch, but other parts of the format are different. Each icon is composed of two images: a foreground image, and a transparency mask.

Identification
Some AIF files begin with bytes.

Others apparently begin with.

Software
