That's wrong. When you change location of a computer (for example) the display attached to it is also auto changed. I've just tested it with GLPI 9.1.2

Also : when you move a name of a location into another one, all devices / assets, etc connected are transfered to the new one.

we can think about OpenOffice which is also an open source app and it does not add line such as "created by OpenOffice" in OpenOffice documents...

great ! thanks

yeah i know but i mean in one action it's not possible

not only for entity but to transfer tickets to another tech

don't have that directory in glpi's directories
