Err, sorry....The first reference to "files" was incorrect. It should read:-
Users/Name/AppData/Local/Google/Chrome/UserData/Default/Files/Log
However, if you are using the Windows folder & file search, it won't reveal these files......I have "Treesize" software installed and it reveals all sorts of unknowns.
The number "files" in the "default" folder seems to vary and, once I delete the "log" file, it takes a couple of days to re-appear. I've tried to paste a screenshot here but it won't allow it.
