Notes about the ULX 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 ULX file type is primarily associated with 'CLAN' by Child Language Data Exchange System. The acronym CLAN stands for Computerized Language Analysis. It is a program designed specifically to analyze data transcribed in the format of the Child Language Data Exchange System (CHILDES).
