// Description:

// \n

// Files are managed by the <code>ContentAccess::CManager</code> class in the content 

// access framework. 

// <hr>

// Some agents may choose to store content files inside their server private directories. For example:

// \private\<process SID>\protectedfile.ext

// If an agent wishes to publish the existence of its private directory, it should fill in the name of 

// the private directory (its SecureID of the process) in the \c opaque_data section of the agents ECOM resource file. 

// CAF will map the path to one based on the agent name so that it's human-readable. For example:

// \private\<agent_name>\protectedfile.ext

// <hr>

// The <code>ContentAccess::CManager::DeleteFileL()</code> allows a client to delete a specified file managed by a DRM agent. 

// The agent responsible for the content can display a dialog to confirm that 

// the user wants to delete the file. This is particularly important if the content still has valid rights.

// The agent implementation must decide whether to delete the rights or only the content.

// TFileName filename;

// // create a manager object

// CManager* manager = CManager::NewL();

// // Use the manager to delete a file

// // CAF will ask the agent who actually owns the file to delete it.

// TInt result = manager->DeleteFile(filename);

// <hr>

// <code>ContentAccess::CManager::CopyFile()</code> allows a user to make a copy of the file. For example, the user may wish 

// to make a copy of the file on removable media. When copying content managed by a DRM agent, the agent will only copy the 

// content, it will not copy the rights.

// TInt result = manager->CopyFile(source, destination);

// <hr>

// <code>ContentAccess::CManager::RenameFile()</code> allows a user to move or rename a file. 

// For example, the user may wish to move the file to removable media. 

// TInt result = manager->RenameFile(oldFilename, newFilename);

// <hr>

// <code>ContentAccess::CManager::MkDir()</code> allows a user to create a directory.

// TInt result = manager->MkDir(fullpath);

// <hr>

// <code>ContentAccess::CManager::MkDirAll()</code> allows a user to create a directory. 

// If one or more of the sub-directories do not exist they will be created too.

// TInt result = manager->MkDirAll(fullpath);

// <hr>

// <code>ContentAccess::CManager::RmDir()</code> allows a user to remove a directory. 

// TInt result = manager->RmDir(fullpath);

// <hr>

// There a three variations of the <code>ContentAccess::CManager::GetDir()</code> function. They each allow a client

// to list the contents of an agent's private directory.

// As mentioned earlier it is optional for agents to provide this information.

// CDir *aDir;

// TInt result = manager->GetDir(aName, aEntryAttMask, aEntrySortKey, aDir);

// <hr>

// The CAF Apparc recognizer provides a MIME type that is a combination of the file MIME type and

// the content within the file. In some circumstances, such as forwarding DRM content to another 

// device, it will be important to make sure the content is sent with the correct MIME type.

// Using the <code>""</code> empty string <code>UniqueId</code> allows an application to determine the MIME type of the file.

// TBuf <256> aMimeType;

// TInt result = manager->GetStringAttribute(EMimeType, aMimeType, TVirtualPathPtr(aURI,KNullDesC16()));

// <hr>

// The <code>CManager</code> API allows applications to retrieve attributes or string attributes from a content object

// <hr>
