How To Enumerate IS Folders ?

Hi All,

I need to get access to stored packages. To do so I use
Microsoft.SqlServer.Dts.Runtime.Application class.
There are methods: Application.FolderExistsOnDtsServer, Application.FolderExistsOnSqlServer
but I need to enumerate existed folders.
Are there something like: Application.GetFolders(String ParentFolderName) ?
I have searched in doc but there is not any useful except:



"To verify that the folder was created, the following Transact-SQL query selects all packages stored in the File System folder of the Stored Packages package store.

select * from sysdtspackages90 "

It is not suitable for me because I don't have permissions to access database

Thanks,
Sergiy
