movefolder = 'downloaded_resumes'
downloadfolder = "Folder_"


imap = Net::IMAP.new(server, 993, true)
imap.login(username, password)
imap.select(folder)


#puts imap.uid_search(["NOT", "SEEN"]).length
count=0
imap.uid_search(["NOT", "SEEN"]).reverse.each do |uid|
file_name="resume_"
no_of_resume=1
# save_attachment
  mail = TMail::Mail.parse( imap.uid_fetch(uid, 'RFC822').first.attr['RFC822'])

#folder dynamic creation
if ((count%no_of_resume)==0 )
dirname="Resume/resume#{count/no_of_resume +1}"
File.makedirs(dirname)

dirname="Resume/resume#{count/no_of_resume +1}"
end
#folder dynamic creation

    File.open(mail.attachments.first.original_filename,"w+") { |local_file|
     local_file << mail.attachments.first.gets(nil) 
#puts local_file.name.inspect
path=local_file.path
filename=File.basename(path) 
extname=File.extname(filename)
loc="resume_#{count}#{extname}"
File.rename(filename, loc)
newfilename=File.basename(loc)
