Read the files contents into our stream object. ISO 9660 (also known as ECMA-119) is a file system for optical disc media. You need to set them accordingly if you use other programming languages. File headers may be used by an operating system to quickly gather information about a file without loading it all into memory, but doing so uses more of a computer's resources than reading directly from the directory information. Over time, many web resources pointed to by hyperlinks disappear, relocate, or are replaced with different content. ISO 9660 traces its roots to the High Sierra Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression. There are problems with the MIME types though; several organizations and people have created their own MIME types without registering them properly with IANA, which makes the use of this standard awkward in some cases. With this type of file structure, tools that do not know certain chunk identifiers simply skip those that they do not understand.
