How widespread is this format? What archivers support it? I would like to replace zip files I create with 7z. But I'm afraid some people will have problems opening them.
Edit: The main reason I want to switch is that zip has problems with encodings on file names. Until recently a lot of archivers did not support unicode zip extension. Many programing enviroments have problem with this.
3Something else to chew on: 7-Zip's GUI self-extraction module is < 150 KB. Chances are your 7z archive will be more than 150 KB smaller than a plain zip archive. – afrazier – 2010-12-09T18:00:00.400
