Read folder list from File system in BLS transaction of SAP MII

Hello SAP MII experts,

I need help in Reading the folder list from file system in BLS transaction of SAP MII. There is getFileList a action block available in MII work bench but it is giving only list of files not folders.

I checked the Catalog service to get the folders list but I think it for getting the folders list of MII Projects only. So is there any way to get the list of folders from the E drive where MII installed.

Thanks,

Subrahmanyam pampana.
