Command
$ fsutil volume diskfree C:

02What it does

fsutil volume diskfree reports three raw byte figures: total free bytes, total bytes, and total free bytes available to the current user (the difference matters with quotas). Unlike Get-Volume it works inside recovery consoles and scripts that must not depend on PowerShell. fsutil has many other read-only queries worth remembering, such as `fsutil fsinfo drives` to list volumes.
