You can use Database File to get the physical file size and Table Information for the size per table. Second one may help you but it's too slow. I am not sure if there is any other place you can get the info you required in Navision. I think best method implementing this is using SQL. As far as I remember there was a built-in procedure which supplys database size related information.

I forgot to mention we are using a C/Side database (not sql server). The physical file size is static (8Go).
Thx for the help,
