I'm trying to figure out exactly what our database size limit in Exchange 2007 Standard is.  I know the registry has been changed to provide more space.  Currently, the registry looks like this:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Exchange2007Server\Private<GUID>
Database Size Limit in GB = 0x000000100 (256)

Does that value mean that the database size is 256GB?  When I look at the properties of this key, the value is 100, but it is the Hexidecimal option.  

I'm wanting to monitor the database, and make sure we are not close to reaching the limit.  Currently, the C: partition has 91.7GB of free space.  When I look at the .edb file in Program Files\Microsoft\ExchangeServer\Mailbox\FirstStorageGroup, the current size of the .edb file is 91.8GB.

Thanks for any insight into this.
