Still filling in gaps after all these years of VCDS. Please excuse dumb questions!

Why does my VCDS folder contain both Scans and Logs of seemingly identical data?
Is the LogLog file really just sort of a catch-all of controller data from different vehicles at different times?
Are faults recorded at 0 rpms important if recorded thousands of miles ago? (will post contemporary scan in the car repair forum soon)

Depends on the circumstances of the fault. If a PDC sensor died overnight, some months ago, you get an error at 0 rpm, thousands of miles ago.
It's a static error, not intermittent, and might very well be active.

On the other hand, if the 3rd glow plug on your TDI decides to have a bit of a bad day, just momentarily, it might show up as an error, thousands of miles ago at 0 rpm.
But flagged as intermittent, not confirmed, MIL not on and all is well.

So it's hard to say without any context.

Logs are where things that you explicitly ask to be saved go.

The Scans folder came about some years ago, when we got tired of hearing, "Yes, I did an Auto-Scan, but I didn't save it." So anytime an Auto-Scan is done now, it silently gets saved to the Scans sub-folder.
