Encryption stopped in middle then Decrypt


Hello, I tried to fully encrypt a passport external portable drive but during the encryption process I still had about 14 hours left, I decided to stop it and start the Decryption process instead because I was afraid of losing any data.
Could you please advise me if all my files, pictures, videos will still be on my portable passport device after Decryption is done? I did not complete the encryption process and decided to start decryption process because I was afraid of losing my files.

Your immediate help is greatly appreciated
