You can download files and folders from a vSAN datastore.
For more information about datastores, see vSphere Storage. The vmdk files are downloaded as stream-optimized files with the filename <vmdkName>_stream.vmdk
. VMware stream-optimized file format is a monolithic sparse format compressed for streaming.
You can convert a VMware stream-optimized vmdk file to other vmdk file formats using the vmware-vdiskmanager command‐line utility. For more information, see Virtual Disk Manager User’s Guide.
