Notes about the IN4 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 IN4 file type is primarily associated with 'InfoBlaster IN4' by UIC Phoenxsoftware. InfoBlaster IN4 is a representation of a portion of the windows registry. You can examine and change many of the more popular items people want to change using the program.
