The file extension CONTACT marks Windows CONTACT files. These files are created by the CONTACT management program built into Windows Vista and Windows 7. An automatically created CONTACT file for each registered Windows user (account) is usually located on the system partition (C :) under Users / * Username * / Contact.
A CONTACT file is loaded by a double click with Windows Contact and is then editable. More CONTACT files can be easily created via the context menu-> new-> contact. In addition to name, address, private and work data, family data and digital identification numbers for email encryption and signing can also be entered.
A CONTACT file is XML-based and can be viewed with any text editor. The name consists of the user name and the extension CONTACT. In addition, the file gets the login picture of the user as an icon. If email addresses are entered, you can also send emails (via action) via the context menu of a CONTACT file (right-click). However, an email program must be installed and linked to this action.
CONTACT files can also be used with Windows Live Mail.
Most often resolving problems with opening CONTACT files is very simple. Just install an appropriate program that supports such files. All of the listed programs support CONTACT files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of CONTACT files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate CONTACT files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Microsoft Windows Contacts applications is not on the list, select "Browse" option in order to manually locate the directory where Microsoft Windows Contacts has been installed.
Sometimes problems with opening CONTACT files may not lie with the application itself, but can arise due to other causes, such as:
