I'd suggest this: Get a list of files first and iterate over it.
Wrap in a begin/end and catch the exception. When you get the
exception for a RO file, explicitly change it to be writable
and do a retry.
Something like:
files = Dir["*.*"]
files.each do |file|
begin
File.delete(file)
rescue Whatever
system("whatever #{file}")
retry
end
end
I don't know the exception or how to fix it in Windoze. Any other
mistakes I made are due to the lateness of the hour.
