On traditional file systems when a file is created/modifed, the directory containing that file gets a timestamp update. Some tools use these dates to understand that the contents of those directories were updated.
Referencing this topic:
I took a look at the API and it looks like updating/patching the timestamps of the folders is supported? If so, what do we think of adding a flag to allow that to happen. I don't think we'd want to do that be default as that would require additional API calls but depending on the use/case it may be acceptable.
Essentially every call to update/create (delete? probably not) a file updates the timestamp on the containing folder to the current date.
Would this break any compatibility? How difficult would it be to create a optional flag?
