Notes about the CLV file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The CLV file type is primarily associated with 'Clovis for Outlook' by Steelhead Systems. Clovis allows users to send and receive secure structured data directly to and from desktops using Microsoft Outlook, Excel and standard E-mail.
