If I use CopyFile to copy a large file to the wolfram cloud (say 100MB), and got say 10 downloads per day (for 1GB/day of download activity), does this consume cloud credits (or cost extra money against most Wolfram/Mathematica subscriptions)?

• Credits are not deducted for file operations like CopyFile, FileExistsQ and fetching cloud objects like CloudGet etc. For evaluating dynamic cloud objects like APIFunction/FormFunction and CloudEvaluate the user credits are deducted. Jan 8, 2020 at 22:46
• @dsingh That looks like an answer! Could you post it as such? It would also be nice if you could point us to a reference that supports that, or show us how you tested it. Jan 9, 2020 at 7:10

We are working on documenting cloud-specific functions extensively. I think its good to specify which functions will deduct credits. I will discuss with my team about it. Thanks

• Thank you for posting it as an answer! Looking forward to more detailed documentation of cloud functions as well. Jan 11, 2020 at 3:23
