Job to decrypt a file and getting following error, what other process is causing the error the only task I have is the decrypt

PGP File decryption error: The process cannot access the file 'D:\SFTP Files\BN\BNTLOGParser\store_s_20180925.zip.pgp' because it is being used by another process.

What settings are you using in the decrypt task?

This error occurs when you want to decrypt to the same folder and The "Base the destination file name on the encrypted file name" checked.
Basically you're decrypting the file into it self, and that why you get the error.

Just use another destination folder or check the "Base the destination file name on inner file namn" and it should work.
