Default Does .mp4 - or any other video format - have a text field (comment, not subtitle)? If so, what can edit it?

John,

_is_ there something intrinsic to the format?


The specs to the format seem to indicate there is, and I found something to
manipulate it here :

And by the way, if you ever wondered what the rightclick - "properties" -
"summary" does: it saves, on an NTFS filesystem, the entered info into a
so-called "alternate data stream", which is attached/linked to your file
but, on XP, not visible when browsing files on (I've been biten by it once,
which is why I know. :-) ).

AFAIK those ADSes will be copied as long as you do it to another NTFS
filesystem (not a 100% sure about it though).


I'm quite sure, NTFS to NTFS copies include all the ADSs. Since other
file systems don't have NDSs, they're lost when copying to FAT, CDS or
any other non-NFTS system.

No idea how a nowerdays
file-packer (7z ?) responds to it. It depends on which one you use and how
old it is I guess.


Hmm...I don't know for sure, but I'd be rather surprised if any of
those handled ADSs.
