In Microsoft System Center Configuration Manager 2007, you add an operating system deployment state migration point folder by adding the folder description to the Directories embedded property list.

The folder description is a string that defines the following information.

Value	Description
Directory	The name of the folder.
MaxClients	The maximum number of clients supported.
MinDiskSpace	The minimum disk space required.
MinDiskSpaceUnit	The minimum disk space units. 1 - MB 2 - GB 3 - Percentage

To add a state migration point folder

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Make a connection to the state migration point resources section of the site control file.
Get the Directories embedded properties list.
Update the Directories embedded property with new folder.
Commit the changes to the site control file.

Example

The following example method adds a new folder to the state migration point.
