DeltaWalker reports different messages differently depending on their severity and their urgency. For instance many tips, warnings, and some errors are reported unobtrusively in the info panel at the top of file and folder comparison windows. Messages that require immediate attention are usually displayed in a modal dialog. Yet others, typically warnings and less severe error conditions, are recorded in the DeltaWalker .log file.
There are two easy ways to access the .log file:
HOME/.deltawalker/.metadata/
e.g.
on Windows that often is C:\Documents and Settings\YourUserName\.deltawalker\.metadata\.log
