What is an ICO file?

An ICO file contains an icon, which is typically used to represent a Windows program, file, or folder. It stores one or more images in various sizes so they can be appropriately scaled depending on their use. ICO files are similar to .CUR files, which are also used in Windows, and .ICNS files, which are used in macOS.

All icons for executable files in Windows are saved in the ICO format. Windows ICO files typically store images ranging from 16x16 to 256x256 pixels. Older ICO files only include images up to 48x48 which was previously the recommended dimensions by Windows. However, most newer icons include images up to 256x256 to accommodate screens with higher DPI.

Each image in an ICO file with less than 32 bits of color depth stores two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. Ama computer university. Images with 32 bits of color are 24-bit images with 8-bit channels for alpha compositing purposes.

When no custom default icon is assigned to a file type, the desktop and Windows Explorer display all files of that type with a generic default icon. For example, the following screen shot shows this default icon used with the MyDocs4.myp file.

While all the files displayed in this screen shot are simple text files, only MyDocs4.myp displays the Windows default icon. This is because the .txt extension is a registered file type that has a custom default icon.

The following screen shot shows a custom icon that has been assigned to the .myp file type.

Note

Icons can also be assigned on an application-specific basis.

For an application assignment, HKEY_CLASSES_ROOTProgID

Remarks

The following example shows a detailed view of the registry entries that are required for a file-type icon assignment. The file name extension is associated with an application, but the icon assignment is to the file name extension itself so that the associated application does not dictate the default icon.

The following example shows a detailed view of the registry entries that are required for an application icon assignment. The .myp file name extension is first associated with the MyProgram.1 application. The MyProgram.1 ProgID subkey is then assigned the custom default icon.

Any file that contains an icon is acceptable, including .ico, .exe, and .dll files. If there is more than one icon in the file, the path should be followed by a comma, and then the index of the icon.
