For random folder names i do

timestamp = Time.new.strftime("%Y-%m-%dT%H-%M-%S%z")
"#{timestamp}_#{("%04x" % rand(16**4))}"

If you want it to be unique, you can use SecureRandom. The simplest way would be using

SecureRandom.uuid

which generates ID like 

irb(main):001:0> SecureRandom.uuid 
=> "0d218853-5ef8-46df-85b1-e7e7af18c0ba"

If you want it guaranteed to be unique, you may want to add timestamp:

Digest::MD5.hexdigest "#{SecureRandom.hex(10)}-#{DateTime.now.to_s}"

which generates

irb(main):002:0> Digest::MD5.hexdigest "#{SecureRandom.hex(10)}-#{DateTime.now.to_s}"
=> "15aaf4a73969c67afccdfdaf629a310e"
