Moving and Accessing SAS Files across Operating Environments

Interpreting a Filename Extension

A filename extension reflects these data file traits:

Engine (V6, V7, or V8) that was used to create the file
Note: The V7 and V8 engines behave identically.
Host architecture on which the file was created
Member type of the file.

Note: All Version 8 hosts, except CMS and OS/390, use filename extensions. See Host Types Supported According to SAS Release for a complete list of Version 8 hosts. For CMS and OS/390, you can use PROC CONTENTS to find out the file's member type and the engine that was used to create it. [cautionend]
Here are examples of filename extensions:

SAS Engine UNIX (HP-UX) OpenVMS Windows

Member of Type DATA

V6 .ssd01 .SASEB$DATA .sd2

V7 or V8 .sas7bdat .sas7bdat .sas7bdat

For a complete list of SAS Version 6, Version 7, and Version 8 filename extensions according to host type, see SAS Filename Extensions and File Headers.

SAS Engine	UNIX (HP-UX)	OpenVMS	Windows
Member of Type DATA
V6	.ssd01	.SASEB$DATA	.sd2
V7 or V8	.sas7bdat	.sas7bdat	.sas7bdat

Note: Version 7 and Version 8 filename extensions are identical. [cautionend]
