Ross in at least one of my flows I write output to a file to be sent to a customer how are you deploying running this flow I m asking how you re running it because most flows are executed in a temporary path which would mean your file would be written to this temporary location if you want to control where your flow runs from you ll need to specify that in deployment

ahh yes thank you for the tips I confirmed it by printing out the `os getcwd ` and indeed my flow is ran in a tmp folder that disappears I also confirmed that if I put a full local directory path instead of a relative path the output goes to the right location too Thanks
