Hello Amol Harde,

Thanks for reaching out!

To list user drives:

GET https://graph.microsoft.com/v1.0/users/48d31887-5fad-4d73-a9f5-3c356e68a038/drives

Java Code Snippet:

GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();

DriveCollectionPage drives = graphClient.users("48d31887-5fad-4d73-a9f5-3c356e68a038").drives()
	.buildRequest()
	.get();

To list children in the root of the current user's drive: This will list all the items (folders and files) along with the Item-IDs present in drive at root level.

GET /me/drive/root/children

Java Code Snippet:

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var children = await graphClient.Me.Drive.Root.Children
	.Request()
	.GetAsync();

To list children of a DriveItem with a known ID: This will list all the sub-items (folders and files) along with the Item-IDs inside a driveItem (folder).

Please note that every item-id is either a file ID or folder ID. The response will have id, name of items and other details. You can identify whether an item is a folder or a file by looking for "files" or "folder" property for that specific Item in response. Refer drive Items resource.

GET /drives/{drive-id}/items/{item-id}/children

Java Code Snippet:

GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();

DriveItemCollectionPage children = graphClient.drives("{drive-id}").items("{item-id}").children()
	.buildRequest()
	.get();

Hope this helps.
