Notes about the PMV 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 PMV file type is primarily associated with 'Pegasus Mail' by David Harris. General filtering rules are in these files. This file type is only used WinPMail 2.20+ and WinPMail v3.x. More current versions do not use it.
