Because SAS
needs to distinguish between the different file types, it automatically
assigns an extension to each file when it creates the file. Also,
because each SAS file is a member of a library, SAS assigns each file
a member type.
The following table
lists the file extensions and their corresponding SAS member types.
CAUTION:
Do not
change the file extensions of SAS files.
File extensions determine
how SAS accesses files; changing them can cause unpredictable results.

A UNIX directory can
store a variety of files, but you might find it more practical to
store files in separate directories according to their use. Also,
you can keep libraries that are accessed by different engines in the
same directory, but this is not recommended. For more information,
see
Using Multiple Engines for a Library in UNIX Environments.
