When using SAS in a Windows operating environment, you might want to specify a list of folders to be used as the SAS Work library. To do so, follow these steps.

1. Locate your sasv9.cfg file:
   
   SAS^® 9.2 location: C:\Program Files\SAS\SASFoundation\9.2\nls\en\sasv9.cfg
   SAS^® 9.3 location: C:\Program Files\SASHome\SASFoundation\9.3\nls\en\sasv9.cfg
   
   
2. Create a TXT file with a list of directories to be used as the new SAS Work libraries. The list should look similar to the following:
   
   
   E:\SASWork
   D:\SASWork
   F:\SASWork
   METHOD=RANDOM
   
   The METHOD= line specifies which strategy SAS is to use for determining the location of the Work library.
   There are two valid settings for the METHOD parameter:
   
   
   METHOD=RANDOM
   METHOD=SPACE
   
   

   When METHOD=RANDOM is specified, SAS selects a location from the list at random, whereas with METHOD=SPACE, SAS selects the Work location from the list that has the most available free space.
   
   

3. Update your sasv9.cfg file to show the location and filename of the TXT file that you just created. The line should look similar to the following:
   
   –work “C:\SASWork\filename.txt”
