When uploading a PPT file from Internet Explorer, the “created time” will be displayed the time which in the image’s properties for a while.
But after a while, when I confirm the file from “Open with Explorer” in the library, the “created time” of the PPT file is overwritten by the file’s uploaded time.
It would be really helpful if the PPT file can be remained to the time which in the image’s properties by “Open with Explorer”.
