- Modern Mac versions have advanced to a new file system format called HFS plus as a replacement of the conventional HFS file system. In this article, I will provide a step-by-step guide on recovering HFS/HFS+ partition but before then, let's have a look at deeper details on the HFS file system.
- The hfss file extension is mainly related to Ansoft HFSS software and used for its default project files. Ansoft HFSS is a 3D Electromagnetic Field Solver which uses Finite Element Methods for S-parameter and full-wave SPICE extraction of high-frequency and high-speed arbitrarily-shaped 3D passive structures.

Can't open a .hfss file?
When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:
Windows can't open this file:
example.hfss
To open this file, Windows needs to know what program you want to use to open it. Windows can go online to look it up automatically, or you can manually select one from a list of programs that are installed on your computer.
To avoid this error, you need to set the file association correctly.
- Open Control Panel > Control Panel Home > Default Programs > Set Associations.
- Select a file type in the list and click Change Program.
The .hfss file extension is often given incorrectly!
According to the searches on our site, these misspellings were the most common in the past year:

The two Introduction to Antennas courses offered focus on the design, fabrication and measurement of microwave antennas. Save time and money by completing these courses exclusively online without the expense of travel.
Get one-on-one personal instruction from an expert and design your own antenna. This is the only online course that offers theory and software design training using the industry-leading High-Frequency Structure Simulator (HFSS) simulation package. The course is ideal for electrical engineers who want to learn about antennas to gain new expertise while having no prior knowledge of the subject. Complete the course at your own pace. For example, four hours each weekend for eight weeks or complete it all in just one week.
The cost includes an electronic copy of the antenna textbook, unlimited access to HFSS during the course period, videos of lectures and notes, videos of HFSS training, videos of fabrication using a milling machine, and measurements using a network analyzer and an anechoic chamber. Upon completion of the lectures, you will be assigned a project to design and test your own antenna. Then, an experienced U of A engineer will fabricate your designed antenna, measure its performance in our lab, and send you the data and the antenna to write your final project report.
Upon successful completion of each course, participants will receive a certificate of completion. Successful course completion also unlocks access to faculty expertise and antenna fabrication facilities at reduced rates for proof-of-concept work.
NOTE - Currently, the fabrication lab is not available for the final project. The course can be successfully completed without this service.
Required: B.S. in Electrical Engineering or B.S. in Physics
If you feel you may have the background or experience to enroll in these courses but do not have the required degree, please contact tdryer@uark.edu to discuss options.
Available Online / On-Demand
