The .c2e file extension identifies an internal dictionary index file for NJStar Chinese Word Processor, a Windows application for writing documents in Chinese characters.
The file contains indexed data for a Chinese dictionary included with NJStar Chinese Word Processor. It supports dictionary lookup within the application and is not a user document or a general-purpose database intended for direct editing.
A .c2e file cannot be opened directly as a standalone document. NJStar Chinese Word Processor on Microsoft Windows uses it as part of its Chinese dictionary data.
A .c2e file is an internal dictionary index and has no standard standalone conversion format. It should normally be kept with the NJStar Chinese Word Processor dictionary files rather than converted.
