File is full and may be damaged.<BR /> <BR /> The log says that 19million observations were read but my data set has about twice that.<BR /> <BR /> I changed the default work folder in SASV9.CFG to an external 2000G drive a while back so there should be enough space. Any idea what is going on? Is there a setting elsewhere that limits the size of these temp work files? Will I have any better luck if I use permanent user files? I'm using EG 4.1.<BR /> <BR /> Thanks,<BR /> <BR /> MBI Tue, 02 Jun 2009 11:57:16 GMT https://communities.sas.com/t5/SAS-Procedures/ERROR-Write-to-WORK-ALL-DATA-failed-File-is-full-and-may-be/m-p/39773#M10272 MBI 2009-06-02T11:57:16Z https://communities.sas.com/t5/SAS-Procedures/ERROR-Write-to-WORK-ALL-DATA-failed-File-is-full-and-may-be/m-p/39774#M10273 I'm providing an update and possible solution in case anyone else encounters this problem ...<BR /> <BR /> I think the issue is the limitation on file size for hard drives formatted using FAT32 which has a maximum file size of 4GB.

Also if possible do send the code which you are trying to execute.
