XDW 3D and 2D files

Hi all

I have to go back to old 2d and 3d achievements from 2004 and 2005 and I came across files with the .xdw extension that I didn't know. After some research on the internet, I saw that this extension could correspond to DocuWork files from Xerox, nothing to do with drawing. I found a viewer but the files are not recognized. Does anyone have an idea? I've already tried imports under Caddoctor, Visi, PTC etc... But it is impossible to open these files.

 

Thank you for your help.
