DB structure

[blondie63]

I'm trying to fix my english categories problems..
Is there a db schema explained?
for example: for table _jdownloads_categories what is the meaning of these fields:
lft, rgt, level ?

Thanks

Hi,
it is not useful to touch this fields and here values.
This fields are required to get the right category sub categories structure and also the right sort ordering.
