How to open GWI files

You need a suitable software like GroupWise to open a GWI file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GWI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GWI file directly in the browser:. Just drag the file onto this browser window and drop it.

GWI file format details:

The file format determines how the data is stored in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below is our analysis of the GWI files:

The GWI file extension predominantly uses a uniform format.

• 100% of all GWI files are based on the Microsoft Compound File format, also known as Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. Compound document files work similarly to real file systems. They contain a number of independent data streams (like files in a file system) which are organized in a hierarchy of containers (like sub-directories in a file system). The file signature of compound files is defined as D0 CF 11 E0 A1 B1 1A E1, so the first character of a file looks like "DOCFILE". Sections and streams in the file have names like SummaryInformation, item type, message id, folder path, user id and version. The files are on average 3 KB in size and range from 3 KB to 3.5 KB. The file type was developed 10 years ago and is still in use today. Such files are related to email, mail, notification, request, revised, form, info, invitation, approval, project, scanned, centre, office, antw and work, and usually contain person-related data.
