#7024 [BUG] [copilot] File extensions are missing when copilot downloads Blob/FlyteFile inputs Issue created by ddl-rliu Flyte & Flytekit version Flyte 1.16 Describe the bug Copilot today has the following behavior:

# ContainerTask, as an example
def t1(file: FlyteFile["csv"]):
    ... # copilot downloads the file to e.g. /inputs/file

Sometimes, this is unintuitive (perhaps a bug? or an enhancement request? not clear...) and it may be expected that the file is downloaded to

/inputs/file.csv

instead. Expected behavior The file is downloaded to

/inputs/file.csv

instead. However, the "bugfix" must be done carefully, as it is likely that existing workflows are already expecting the file to be downloaded to

/inputs/file
