### FILES

This command specifies the files that are to be copied from the source directory to different destination directories. It performs in a manner similar to the DDINSTAL :FILES command. Like its DDINSTAL counterpart, the DSPINSTL :FILES command line is followed by a set of file copy directives. However, unlike its DDINSTAL counterpart, the DSPINSTL :FILES command uses the UNPACK utility program to copy files. Therefore, it can handle both packed and unpacked file formats.

The :FILES command can be used to replace any executable modules (programs and DLLs,) that are currently in use. The replacement occurs the next time the system is started. DSPINSTL cannot replace nonexecutable files that are locked at the time DSPINSTL is run.

To protect against inadvertently copying an older version file over a newer version file, all file copying is mediated by either one of the following forms of file version checks:

File Version Field checking
Date/Time checking
