Line 25: PDS/E file structure is similar to PDS files and is used to store the same types of data. However, PDS/E files have a better directory structure which does not require pre-allocation of directory blocks when the PDS/E is defined (and therefore does not run out of directory blocks if not enough were specified). Also, PDS/E stores members in such a way that no compression is needed to reclaim dead space. PDS/E files can only reside on disk in order to use the directory structure to access individual members. PDS/E files are also referred to as Libraries. [[category:~~IBM~~Computer ~~storage devices~~data]] [[Category:Data management]] [[Category:IBM Mainframe computer operating systems]]
