Disregarding "
folders" & disregarding "on a drive cloud", 3:Replace, could cover the renaming of file names.
With 3:Replace, you'd have to watch out for matches that while they may match, are not matching what you intended.
Like if you wanted to replace "page" with "XXX", you might have a name like "offline web page" that is OK to change to "offline web XXX",
but you might also have "his pager" where you would not want that renamed to "his XXXr".
(If that were the situation, you'd have to try an alternative means, like by using 1:RegEx.)
I don't really know about "clouds", but if the "cloud" provides an interface that is accessible to BRU then I'd think you could do that part too.
And if not, then you'd have to find something else to handle that part.
