Hi,

I recoverd my data but I have to reinstall programs. It is a good occasion to make a nice clean...

Yes it is possible that PlanG was not the cause of the folder content or adressing deleting. It's may be a coincidence and the deliting occurs in the same time I installed Plan G. But we wil never know... I will retry later the PlanG installation and come back on the forum.

The PlanG installation program has deleted ALL THE PROGRAMS installed on external disk Programs file directory...
