Notes about the HFT 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 HFT file type is primarily associated with 'HaftiX' by GRZELA Grzegorz Zochowski. [Polish site] HaftiX is a computer program that converts any graphics, video, or photos into embroidery patterns. It shows how the embroidery will look. It has a tool for editing and minimizes the number of colors, calculates use of thread and its cost, creates designs with user-selected color, prints them, etc.
