There have been a couple of instances where a user has uploaded files via a portal. The files appear to be renamed. Is this common place or is there a setting issue somewhere? If this is correctable, please assist on how to correct this.
Example:
Original: file name.pptx
Renamed: file name (f8678811-68r0-4c2f-b5b3-2dc5e8dff922).pptx
