Enumerates Path for media database tables created by a Recording Server.
The records returned by this function must represent media database folders with names matching the format used by Milestone. The format expected is GUID_TAG_TIMESTAMP where GUID is the id of a device, TAG is a string like LOCAL or ARCHIVE, and TIMESTAMP is a local timestamp in the format yyyy-MM-dd_HH-mm-ss.
Each record returned by this function will have a DeviceId property of type [Guid], an EndTime property of type [DateTime] which will be a local timestamp representing the approximate time that folder was last added to, a Tag property representing the LOCAL or ARCHIVE string value describing the type of table, and a Path property with the full path to that folder on the file system.
This function does not rely on cache.xml or archives_cache.xml in any way. As such, it can be used on a system with an invalid or missing cache. However, the accuracy of the timestamps is unreliable because they are based on the names of the folders on the filesystem which represent the time the Recording Server renamed that folder when it was converted from a live media database table to a local archive table.

Copy all media database tables for device with ID 94275fef-b977-43f6-bf78-210c615b2967 to C:\Temp
The GUID of one or more devices you want to retrieve tables for. If you omit this property, all tables for all devices will be returned.
The local DateTime indicating the last records to be retrieved from the media database. Since entire folders, each containing approximately one hour of video, will be retrieved, you could end up with video up to one hour newer than requested.
The path to the media database. This must be the path to the folder containing the media database tables. For example, C:\MediaDatabase\4344cd14-0b12-4c18-8677-5d263c140af4 is the full path to the default "Local default" storage path. The ID for yours will be different, and if you need to find the ID, you can hold CTRL and click on the Storage tab of the Recording Server in Management Client. Then hover over the storage configuration and you will see the ID displayed in the tooltip.
The local DateTime indicating the oldest records to be retrieved from the media database. Since entire folders, each containing approximately one hour of video, will be retrieved, you could end up with video up to one hour older than requested.
