Landing in MediaBin in specific folder while browsing from Teamsite

merry

Hi,
I am using ECM connector to connect to MediaBin (4.6.1 Build 7) from Teamsite (6.7.1). When I click on Browse button, the control goes to the root folder. How can I direct it to a specific folder? I tried to use the "path" parameter, but not able to figure out which path should be provided as a value. The snippet is:
< item name="test_path" pathid="test_path" >
< label >Test_path:< /label >
< description>
< text size="35" maxlength="100" >
< default >/Folder_Name/Subfolder_a/Subfolder_a/< /default >
< /text >
< /item >
< dialog-param name="path" >
< dialog-input>< field-ref name="test_path" />
< dialog-output>< field-ref name="test_path" />
< /dialog-param >

I have tried giving the absolute path for the image in Mediabin, but couldn't do it successfully.
Please help me with the same.
