Appendix C: Default File Types

If you omit a file type in a file specification, OpenVMS may assume a certain file type, depending on what command you issued. For example, the SET COMMAND utility assumes a file type of .CLD.

The command

     $ SET COMMAND UTILITIES 

is interpreted as

     $ SET COMMAND UTILITIES.CLD 

Common default file types are listed here:
