Where are the Files uploaded to KM stored, in database or some location

Hi All,

Say for example we have created a pdf file and uploaded this to KM Folder in the portal server.

How and where this files stored in the server.

Whether they are stored as objects in the database or in any location of the hard disk as a file system.

If in database, please let me know the table name and how to access it.

If in the hard disk, then please provide me the location.

Thanks in advance,

Ramanath
