I want to run an after update opportunity trigger that would fetch all the opportunity records as well as attachments and then transfer it to a third party-website. In order to do that, I am first trying to fetch the salesforce data and attachments with some free tool/code and upload it to FTP site/Google drive. From FTP/google drive I would pick the data and get to the third party site.
My question: Can I extract attachments using Command Line Dataloader and use ANT to send it to FTP site or Google drive. What format would the attachments be extracted using Dataloader? I don't want to use any paid tool e.g. Jitterbit e.t.c, since I don't have the budget for that. So I am wondering if Command Line Dataloader would be good enough to extract attachments?
