Notes about the CLE 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 CLE file type is primarily associated with 'Icon Lock-iT' by Moon Valley Software, Inc.. The .CLE extension designates a file locked by Icon Lock-iT (French 'cle' meaning 'lock'). It is a hidden extension that changes the icon to a locked icon. The extension is attached to the existing file type prompting Windows to alter the icon in response.cIt is not a true file type, does nothing more than designate a locked icon
