File does not exist

[_maldini_]

I have multiple SAS datasets in a folder using SAS University Edition. I can load all of the dataset except for one. I get an error: "File CARDIA.UCSFMEDFEB2013.DATA does not exist."

I am able to load other datasets in the same folder: 

 There is nothing different about these datasets other than the contents and the size of the files. The dataset that can't be found is actually smaller. 

A friend can load this dataset without problem using a desktop version of SAS.

Any ideas as to how I might be able to resolve this problem?

Thanks.

Make sure the actual file on the disk is using only lowercase letters in its name.

You are probably using UNIX and your friend was using WINDOWS.  The WINDOWS file system is case insensitive.  So FRED.sas7bdat and fred.sas7bdat would be the same physical file.

But on UNIX the file system is case sensitive.  

SAS syntax does not care if you use FRED or fred as the member name.  To make it work it lowercases the name when it goes to the operating system.  So both references in SAS will be looking for an actual operating system file named fred.sas7bdat.
