DrawPlus

Serif DrawPlus is a vector graphic program. DrawPlus X8 released in 2015 was the last version, replaced with the new Affinity software. DrawPlus saves its documents as .DPP (Drawing), .DPX (Template) or .DPA (Animation) files (for Stopframe and Keyframe animation modes). Drawplus X3 and above can also export into a Serif MetaFile (.SMF) format.

File Identification
DrawPlus version 1, or Intro, file headers begin with "{{Magic|V{DrawPlus Picture V1 DP}}"

DrawPlus version 2 file headers begin with "{{Magic|V{DrawPlus Picture V2 DP}}"

DrawPlus version 3-X2 files are based on the "OLE2" document container format.
