  dcterms:description "The Icon file format (ICO) is a graphics file format for computer icons (as well as an image file format for favicons). It was developed by Microsoft for computer icons as part of its Windows operating system and also later supported for browsers to varying degrees in its favicon usage, starting with the release of Internet Explorer 5. ICO files serve as an icon resource that can be a container for multiple images (i.e., BMP or PNG) and the file format also was extended to the CUR file format for Windows' non-animated cursors—both ICO and CUR files have a directory structure. ICO is proprietary and is still in use by Microsoft as a native file format. Due to the prevalence of the Microsoft Windows operating system and its ability to render most ICO files, along with the particular structure of ICO files and how they might relate to other files in context of their usage, it is recommended to retain them as is, with the caveat that ICO files created 1987-2001 (with emphasis on 1987-1995) may possibly originate from the OS/2 operating system and/or contain files from the OS/2 Bitmap family. If this is the case, it is ideal to determine if they can still be rendered in a current Microsoft Windows operating system and if not, converting ICO to PNG can be considered as a possible approach but more research is also needed." ;
