I received a specification file from an architect via FTP this week that was 60MB in size.
Running it through the "Compact specification" tool within the NBS Building software it reduced to 12MB.
Why is this operation necessary?
The database format used for NBS Building is MS Access. When you delete a record from a MS Access database, the space allotted for that record continues to be held in reserve by the database and it is not released for reuse. To avoid generating excess amounts of wasted space, you should compact your database periodically.
