It may be a flaw in TYPO3 itself, but when moving a file in fileadmin, FAL is invoking extractors to extract metadata again which is totally wrong, it should be done during upload (if configured so for the underlying storage) but never afterwards.
Problem is that if a user changes the metadata by editing them, they will get overridden whenever the file is moved around!
Will need to investigate but at first sight, it seems the extraction is invoked by TYPO3 itself. I need to double check if it's not somehow related to EXT:file_list which is reacting to many if not all FAL events as well.
