i have a brother SE600 and just cannot seem to get purchased fonts into my machine.  I purchase, download, unzip, copy the PES file to my flash drive then when i insert into machine it displays folders (side, middle letters) but cannot view any letters or open the folders.

I have used all the monogram fonts that came on my machine and want a fancier monogram for granddaughter.  

Hope someone can tell me what I am doing wrong!

Brother SE600 embroidery machine has a hoop size of 4 hours 4 inches. Before you copy files to a flash drive or USB card, you need to check the size of the machine embroidery file designs. This can be done on the product page.

You can also use free embroidery software. For example, my editor. 

It is important to remember that none of the design sides should exceed 3.98'.
