What is an udc file and how do I open an udc file?
An Adobe InDesign user dictionary file is used by the InDesign software that was developed by Adobe Systems, and the content of an Adobe InDesign user dictionary file may consist of a list of words and phrases that can be referenced by the Adobe InDesign application when a user requests access to the grammar and spell checking functionalities implemented into this page design and desktop publishing program. Users can define words and phrases as well as exception rules that can be stored in these Adobe InDesign user dictionary files. Text formatting standards and data encoding specifications are integrated into the content of an Adobe InDesign user dictionary file so it can be stored in the UDC file format, and the UDC file format along with these text formatting attributes and data encoding standards are all proprietary to Adobe Systems. Words stored in compatible dictionary files can also be entered into these Adobe InDesign user dictionary files. A file in the UDC format is affixed with the .udc extension. These UDC files can be used for groupware collaboaration, since a Adobe InDesign user dictionary file may be shared with many users.
