They are also used as backup files as users can copy these files into another folder or disk should the need arise. Users can open .wab files with the use of applications such as Microsoft Windows Contacts, Microsoft Outlook Express, Microsoft Outlook 2010, Microsoft Internet Mail and News, Connected WabOut, etc.

Microsoft Outlook Express

Microsoft Outlook Express

Outlook Express is an email and news client that is integrated with Internet Explorer versions 4.0 through 6.0. It is also bundled with a number of versions of Microsoft Windows, from Windows 98 to Windows Server 2003, and is available for Windows 3.x, Windows NT 3.51, Windows 95 and Mac OS 9. In Windows Vista, Outlook Express was outdated by Windows Mail, then again by Windows Live Mail as separate software in Windows 7. Microsoft Entourage, sold as part of Microsoft Office for Macintosh, has changed the Macintosh version. Outlook Express is a diverse application from Microsoft Office Outlook. The two programs do not share a common codebase, but do share a common architectural philosophy. The similar names lead many people to incorrectly conclusion that Outlook Express is a stripped-down version of Microsoft Office Outlook. Outlook Express utilizes the Windows Address Book to store contact information and incorporates tightly with it. On Windows XP, it also joins together with Windows Messenger.

a word of warning

Be careful not to rename the extension on .wab files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .wab. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
