"Need Update" flag?

Hi,

We use EDrawing program to other machines in factory. But I want to keep update state of all drawinf files. To do this I write VB. NET API program. The program open all the drawing files in directory and save it and close.

But it takes time ofcourse. I want to save only the drawing which is need to be save!

Is there "Need Update" flag of drawing files? I want to save only the drawings which need to be save, need to update!

Reards,
