Understanding Drive Hierarchies

At the root of every data tree is a "Drive" entity. When a drive is created, a Root Folder is also created for it. The entity IDs for both are generated and returned when you create a new drive:

ardrive create-drive --wallet-file /path/to/my/wallet.json --drive-name "Teenage Love Poetry" |
tee created_drive.json |
jq '[.created[] | del(.metadataTxId, .entityName, .bundledIn)]'
[
    {
        "type": "drive",
        "entityId": "6939b9e0-cc98-42cb-bae0-5888eca78885"
    }
    {
        "type": "folder",
        "entityId": "d1535126-fded-4990-809f-83a06f2a1118"
    }
]

The relationship between the drive and its root folder is clearly visible when retrieving the drive's info:

ardrive drive-info -d "6939b9e0-cc98-42cb-bae0-5888eca78885"
| jq '{driveId, rootFolderId}'
{
    "driveId": "6939b9e0-cc98-42cb-bae0-5888eca78885",
    "rootFolderId": "d1535126-fded-4990-809f-83a06f2a1118"
}

All file and folder entities in the drive will be anchored to it by a "Drive-ID" GQL Tag. And they'll each be anchored to a parent folder ID, tracked via the "Parent-Folder-ID" GQL tag, forming a tree structure whose base terminates at the Root Folder.
