Notes about the UPM 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 UPM file type is primarily associated with 'PenMail' by UC-Logic Technology Corp.. PanMail is part of UC-Logic's PenSuite which is a collection of out-of-the-box tools and utilities for users to explore the functionalities of their PC tablets, and allows them to experiment with annotating and signing documents, basic painting and drawing, composing and sending handwritten E-mails, and make digital whiteboard presentations, without the need for third party application software.
