Files come in both MTC (Make The Cut) & SVG (Scalable Vector Graphic), SCAL V2 (Sure Cuts Alot Version 2) & Silhouette V3 Formats in a compressed Zip File with a Color & B&W Picture in JPEG format, alos a Color PNG, which is simply a "screen Shot of the "cut File" some come with just B&W JPEG others come with both B&W and Color JPEGS for tracing and reference.
They are in a compressed zipped file and need to be extracted before being able to open the file properly in supporting software. You need an electronic die cut machine with software that can read/open either an MTC or SVG or SCAL V2 or Silhouette V3 format file.
Until Next Time...
