How to check the file is available or not.
write this simple code for checking the file.
but if file not found they print the first condition.

if(contents = File.read(“c:/test/test.txt”))
log.debug “Text File Available…!!!”
else
log.debug “File not Available”
break
end

You can do this with File.exist?("…"), but I’d do this:

begin
contents = File.read(“c:/test/test.txt”)
log.debug “Text File Available…!!!”
rescue Errno::ENOENT
log.debug “File not available”
break
end

This is technically better because it avoids a race condition (the file
being deleted within the short time between when you test for its
existence, and when you actually read it)

There is File.readable?(name)
but who knows if it actually works in windows…if you’re not on windows
it probably works fine.
