If I purchase a embroidery design like the one in this link will I be able to view it in my Wilcom Truesizer program embroidery software, as I was looking to purchase a pattern before and was told I needed it in PES for my brother se400 and Emb to be able to view with Wilcom software. Also when I look at the following embroidery design it shows four sizes, does it come with all of them or do I need to choose just one size hoop from this link Miami Dolphins 2013 logo embroidery design

Hello

Yes, PES machine embroidery format available for download. but need check hoop size. EMB format not available. This is original files, only stitches files to embroidery machines. 

About four sizes please read here Hi i selected the pes for the format that i have purchased, it gave me several choices differentiated with a, b, c, d, etc. at the end of the design name. What do these letters indicate?

Cheers
