Does Maxell Data Compression Software compress already compressed files?
To better answer your question, I would like to explain a little about file compression. Compression techniques vary in their ability to compress different types of files, but the idea behind each method of compression is the same. Compression programs remove unused or redundant portions (like repeated characters or colors) of a file, reducing it to its minimum. That is why .BMP files compress so well (every single bit is stored, even for blank spaces) and .JPG files don’t compress very much (the format includes color compression).
