System Internals "Snapshot" app ?

I have just found System Explorer and in particular Snapshots

I assume "System Explorer" is a management tool for System Internals Suite, because of the implied comments (or my wishful thinking). I cannot find any cross-references.

Does anyone know if SystemExplorer is related to System Internals ?

Snapshots (SystemExplorer) sounds like a very handy tool , but I cannot locate it in SystemInternals downloads nor in Sysinternals Utilities Index
I have a gnawing feeling the answer is on this post already.

Hopefully somebody can steer me to SnapShots or an equivalent.

Thank you in advance :)

Thank you for such a prompt reply :)

I will test SystemExplorer to see how "SnapShot" works and if it delivers, as implied in SystemExplorers web-site.
