Hello
I think it's possible with Batch Properties, except that you will have to know the name of all the properties in advance to be able to delete them!
Not very practical indeed!
Otherwise, I agree with what Coyote said, Integration is more suitable.
Or create a macro!
Effectively you can use * as the property name to be deleted
This will erase any properties or
*foo to delete the one whose name ends in foo
foo* to erase the one whose name starts with foo...
Also look in the options to set if you clear the properties of the
document or configurations
