The Icon Librarian

Latest revision as of 13:45, 6 November 2025

The Icon Librarian, by Keith Ledbetter, is a Windows 3.x program for making collections of icon graphics.

[edit] Format details

The program lets the user create multiple "libraries" of icon graphics. It maintains a single global ICONLIB.ILG file, and multiple .TIL files. A TIL file contains the graphics for one library. All other data, such as the names of the libraries, is stored in the central ILG file.

A TIL file is apparently just a sequence of structures, 744 bytes each. The structures resemble DIBs, but are not actually in that format. A DIB would be 1128 bytes in size, not 744.

[edit] Identification

ILG: Unknown. Identification might be possible, but the format doesn't seem to have any distinctive markings.

TIL: It seems possible to distinguish TIL from DIB. The file size is a multiple of 744, and the same 40 bytes, beginning with (hex) 28 00 00 00 20 00 00 00 40, appear every 744 bytes.
