Notes about the PEH 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 PEH file type is primarily associated with 'Power Email Harvester' by YesGoal LLC. Bulk E-mailing program that both collects addresses and mails to those addresses.
