Why convert XXX to EXP?
XXX is the Singer/Compucon format, read by Singer Futura series machines and Compucon EOS software. Convert to EXP when your Bernina or Melco machine expects EXP. SewFlow re-encodes your existing stitches for the new format — it never re-digitizes, so the design sews out identically.
What happens to thread colours
EXP files don't store thread colours — the format stores raw stitch data with no thread-colour table. Your stitch order and every colour stop are preserved exactly; you assign the actual thread colours at the machine, matching the free preview shown before you convert.

Frequently asked questions
Will my design stitch out the same after converting XXX to EXP?
Yes. SewFlow re-encodes the same stitches rather than re-digitizing: stitch paths, jump and trim commands, and colour stops are preserved exactly, so the EXP file sews out identically to the original XXX design.
Which machines read EXP files?
EXP (Melco Expanded format) is read by Bernina home machines and Melco commercial embroidery machines. Load via USB. EXP carries stitches and colour stops only, so you set the actual thread colours on the machine.
