Notes about the PUI 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 PUI file type is primarily associated with 'Foobar2000' by Peter Pawlowski. Foobar2000 is an advanced audio player for the Windows platform. Some of the basic features include ReplayGain support, low memory footprint and native support for several popular audio formats. Panels UI is a GUI for customizing the appearance of foobar2000 through the use of titleformatting scripts; these include Panels UI's own host of titleformat functions and variables, as well as core foobar2000 functions and fields.
