File Folder on BPC server

Hi,

We have a requirement where w have to drop a file from external system into BPC folder structure where from we can load it to BPC.

Say following is the link which we can see in out DP Manager:

HTTP://XXXXXXXXX:8000/APPSET/PLAN/DataManager/DATAFILES/Price

where does this folder structure reside? ABAP or BW or .Net Server? and How can we find it.

Please let me know.

Thanks,

Diksha.
