When creating a volume shadow copy of a drive, e.g. by calling wmic shadowcopy call create Volume=c:\, a snapshot of all files is stored in the "System Volume Information" folder.
Older snapshots are deleted automatically, to make room for new snapshots
I can display how much space all file snapshots consume in total: vssadmin list shadowstorage
(As far as I understand: if a file does not change between snapshots it does not consume any significant space.)
Can I display the used space, per file or per folder?
e.g. I want to know how much shadow storage space is consumed by c:\path_1\*.* or c:\path_2\file.3, across all snapshots.
The goal is to fine tune shadow storage, by excluding paths with lots of unimportant changes using the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\BackupRestore\FilesNotToSnapshot
