Moving and Accessing SAS Files across Operating Environments

Determining the SAS Release Used to Create a Member

OS/2 and Windows Filename Extension by Member and SAS Release identifies the supported file types that are created on the OS/2 or the Windows host by member and by SAS release:

OS/2 and Windows Filename Extension by Member and SAS Release
Member Type Version 6 Filename Extension Version 8 Filename Extensions¹

(Short) (Long)

SAS .sas .sas .sas

PROGRAM (DATA step) .ss2 .ss7 .sas7bpgm

DATA .sd2 .sd7 .sas7bdat

INDEX .si2 .si7 .sas7bndx

CATALOG .sc2 .sc7 .sas7bcat

MDDB .sm2 .sm7 .sas7bmdb

DMDB .sb2 .s7m .sas7bdmd

PROC SQL view .sv2 .sv7 .sas7bvew

***OS/2 and Windows Filename Extension by Member and SAS Release***
Member Type	Version 6 Filename Extension	Version 8 Filename Extensions¹
(Short)	(Long)
SAS	.sas	.sas	.sas
PROGRAM (DATA step)	.ss2	.ss7	.sas7bpgm
DATA	.sd2	.sd7	.sas7bdat
INDEX	.si2	.si7	.sas7bndx
CATALOG	.sc2	.sc7	.sas7bcat
MDDB	.sm2	.sm7	.sas7bmdb
DMDB	.sb2	.s7m	.sas7bdmd
PROC SQL view	.sv2	.sv7	.sas7bvew

Version 8 and Version 7 filename extensions are identical.

Furthermore, you can use the CONTENTS procedure to display information about the data, which identifies the member and the engine that was used to create it.

Here is an excerpt of typical PROC CONTENTS output:

The SAS System
    The CONTENTS Procedure
Data Set Name: TEST.CONTENTS
Member Type:   DATA
Engine:        V8

This output reports that the data set TEST.CONTENTS is a member of type DATA, and that it was created with the V8 engine.
