What exact do you refer the concept of FILE here?
 
if it is a element in SAS system, such as a SAS dataset, a SAS frame, etc..
you can look up SASHELP meta tables.
 
if the FILE is a host system file, such as a UNIX file, then you have to use
SAS interface to the host, issue UNIX commands to pass the found or not
message back to SAS.
