Re: Cocoa framework or Object class to uncompress files

No. There’s no solution there. The Archive framework makes uncompressing of raw data easy, including the compression format that’s normally used inside .zip files, but it doesn’t actually read .zip file format. The file format and the compression algorithm are, in effect, unrelated to each
