== The Anatomy of a Hyper-V Snapshot ==
When a snapshot is taken of a Hyper-V virtual machine, a number of files are generated. These files are stored, by default, in ''%SystemRoot%\ProgramData\Microsoft\Windows\Hyper-V\Snapshots''. The ''ProgramData'' folder is typically a ''hidden'' folder and as such will not be visible in Windows Explorer. To view the folder and its contents, therefore, select ''Tools->Folder Options...'', select the ''View'' tab and enable the option to ''Show hidden files and folders''. The default snapshot file location may be changed on a per virtual machine basis by selecting the virtual machine in the Hyper-V Manager list, clicking on the ''Settings...'' link in the Actions panel and modifying the ''Snapshot File Location'' value in the ''Management'' settings section.
Each snapshot consists of the following files:
* '''Configuration file''' - An XML file containing the current configuration settings of the virtual machine.
* '''Saved state file''' - A ''.vsv'' file containing vietual machine state information.
* '''Differencing disk image file''' - A ''.avhd'' differencing disk.
* '''Memory image file''' - A ''.bin'' file containing an image of the virtual machine's memory at the point the snapshot was taken.
