It will then create a file with the same name and in the same directory but with a file extension of .cryptra. So if you want to send a file named "Test.txt", you run it through CRYPTRA and it will produce an encrypted file named "Test.cryptra" and this is the file you send. CRYPTRA will also keep track of the OTP files that have been used and how many remain for you to use. CRYPTRA has been designed to be extremely easy to use.
