I can think of at least one good reason for putting movies
, etc. in a .zip archive
Quite a lot of compression formats (mpeg
, etc.) will fail silent
ly if they become corrupt
ed, or shortened, the errors showing up as blips in the audio, or artifact
s on the screen. Or even just the tail end of a song going missing.
file, on the other hand, contains information on the expected filesize, and CRC
for each file. If the archive
becomes damaged you'll know about it. And if you don't want it in a zip, you can take it out again. A processor capable of playing Divx
, or mpeg video can easily cope with unzipping a file, and packages like zipmagic
make the process transparent. For a minimum of inconvenience, you gain a lot in data security.
And it might even save a few bytes
