To prepare the storage of files (designs), first create at least one new folder on your PC hard drive and name it Embroidery Designs.
As you collect designs, you can then divide them into name specific folders.
Send the zipped files to the folder, then highlight and choose open or extract. The extracted file is what you will be converting to that required by your embroidery machine...for your machine you know it has to be .jef.
When you go to Download Designs, on the screen that will open after agreeing to the guidelines, there will be links to other software.
Download Pulse Ambassador (it's free). This program will allow you to open the design from the folder on the hard drive.
You then choose Save As and select the format you need.
