For large files, copy via Remote Desktop is a troublesome thing, though simple, but the speed is limited too, is not recommended.
I work for copying large files, by creating a new virtual hard disk (VHD), and then copy a large file to a virtual hard disk, and finally attached to the virtual machine.
This not only saves time, but also improves the reusability, a virtual hard disk can give more than one virtual machine (note: the same time only one virtual machine can use this file).
Create a virtual hard disk
Into your operating system (such as Windows Server 2008 R2), open the Disk Management
Click Disk Management, create a VHD and select the storage location and size of virtual hard disk
At this point, you can see the disk management interface out of a new disk, then attention has not been initialized.
Initializes a newly created disk
Then, the New Simple Volume
After running the wizard is finished, then turn it on and go to the big file copy, you can see that I've successfully created a 10G hard drive
Finally, the separation of the virtual hard disk
Annex virtual hard disk to the virtual machine
Select the virtual machine, select the setting, the hard drive will build up additional virtual hard disk, and then apply, can be determined.
Finally, log in to the virtual machine, virtual hard disks attached success under examination.
