Thanks for the 7z hint, but i guess i have to update first: my version 3.0 does not have this feature.
It's not a trick, more a suggestion, since it can be very annoying:
- Do not use any compression when packing videos.
Now and then you find archives that take very, very long to extract. Mostly because different compression levels are used. Videos are already compressed by their video codecs so you hardly see any difference in the filesize, but it takes a lot of time not only to extract but also to pack the files.
Same with most of the pics. Only for high quality jpgs (100%) a moderate compression might be helpful.
This option can be modified via settings/compression standards: just choose "store" instead of any compression.
Another thing is "authenticity information":
- Do not add "authenticity information" to your files
This option, as far as i understand it, is only useful when you pack files for storing purposes on your pc, not for distribution. It adds a kind of digital signature to the files and is only valid if you open it on the pc where it has been created.
If another one opens the files on his pc, he gets an error message, very annoying with multiparted rars.
