How to verify a file after copying?

[snapraidowns]

I searched and out found this:

*************
> Does FFS doe a file verification after copying? Yes, although this feature
is not really advertized: You'll need to open a sync-config file (*.ffs_gui)
with an editor and set XML node "VerifyCopiedFiles" to true. This adds an
unbuffered binary comparison after a file is copied.
*************

However, I have no clue how to do what you suggested, or where the sync-config
file is located.
Searches for "sync-config" here turn up different things.
Thank you

There has been some change meanwhile. It's now in "globalsettings.xml"
