File management APIs allow you to perform general maintenance tasks for
files in hierarchical file systems. The file management APIs are:
Copy Stream File (QHFCPYSF) copies an existing stream file into another stream file and optionally renames the copy.
Delete Stream File (QHFDLTSF) deletes a single stream file. Both the directory entry associated with the file and all data contained in the file object are deleted.
Move Stream File (QHFMOVSF) moves a single stream file from one directory to another and optionally changes the file's name. The file's attributes are not changed.
