Namespace limits
Applies To: Windows Server 2003 R2
When adding folders to namespaces, keep the following recommendations in mind:
For stand-alone namespaces, we recommend a maximum of 50,000 folders with targets.
For domain-based namespaces, we recommend keeping the namespace object in Active Directory to 5 megabytes (MB) or less (equivalent to about 5,000 folders with targets).
Note
Folders without folder targets do not count against these limits.
To make it easy for you to check the size of your namespace, the namespace size is shown in the Namespace Properties dialog box. To view this, right-click the namespace in the console tree, and then click Properties.
