BPM for multiple accounts sender..

We have a scenario where we get a list of accounts from a sender file. THese accounts(will act as logins) will be used to retrieve files from their respective Unix directories. I was thinking if BPM is the only option here. To read account from the sender file and create a connection to the unix folder and send all the files to the receiver folder. Then it goes into a loop and picks up the next account from the sender file.

Any better way of designing such an interface without BPN or is BPM the only option??
