hmm. careful w this command, it recurses. and watch for symlinks too.

of course, there is really something wrong in there. let's fix it :)

> Is there any way I can speed this up?

you are scanning the folder for every file, so 10 file renames results
to 10 (re)scans of those 100k files.

correct me if i'm wrong, but i think you do not need  to scan the
folder. just chdir to that folder. loop on your csv and do the inner
rename. let the os do the search and the rename. i bet 10 renames wont
even take 10 seconds :)

something like, (untested)

Dir.chdir folder_to_change
csvfile.each do |old, new|
  File.rename(old, new)
end
