What is a U01 file?
A U01 file (.u01) is the Barudan U01 machine embroidery format, used by Barudan and some other commercial machines. It stores the stitches, jumps, trims and color changes of a design but not the thread colors themselves. You can't open it in an image editor: view it in an embroidery file viewer, load it on the machine by USB or Wi-Fi, or convert it to another format.

What's inside a .u01 file
- Every needle position, in order
- Jumps and trims between areas
- Where each color starts (color stops)
- No thread colors: only where they change
U01 is the format of Barudan's commercial multi-needle machines. Like DST, it records needle movements, jumps, trims and color stops.
It doesn't store thread colors: you assign needles at the machine, so keep the color sheet with the file.
Most Barudan machines also read DST, so DST is a safe fallback if a shop asks for either.

How do I open a U01 file?
Open it in an embroidery file viewer: drop the .u01 file into Embrizo's viewer to see every stitch, the colors and the size in your browser. Image editors and PDF readers can't open stitch files.
Does a U01 file keep thread colors?
No. U01 only marks where colors change. Keep the color sheet with the file and assign threads at the machine.
How do I convert a U01 file?
Open it in the embroidery file converter and save it as DST, PES, JEF, EXP, VP3, XXX or another format. Converting keeps every stitch; only the container changes.
Can I make a U01 file from a picture?
Yes. Upload a PNG, JPG or SVG to the Embrizo digitizer, check the stitch preview and save a U01 file for your machine.
