What does the command tf vc scorch do?

Question

In the build logs of TFS builds I have seen the use of the command tf vc scorch. This looks rather interesting and seems to be something like git clean and could be quite helpful but for some strange reason scorch is not documented. Is this some internal thing that is not intended for public use?

Typing tf vc /? does not list the scorch command and tf vs scorch /? does not explain the parameters. It is also not listed on docs.microsoft.com.

Where can I find its full documentation?

Answer 1

Adding a "/?" to the command line will give you a description of the command and its parameters

tf.exe vc scorch /?

Result is:

tf vc scorch [/diff] [/noprompt] [/preview] [/recursive] [/ignore] [/unmapped] [/exclude:itemspec1,itemspec2,...] [itemspec]

Addition 23/10: with the help of the link supplied by Andy-MSFT clarifies that adding /diff will force the algorithm to diff files that are still read-only to make sure that they are in fact unchanged from the workspace version.
