Usage Note 40934: Retrieve file size, create time, and last modified date of an external file
 |  |  |  |  |  |
Starting in SAS® 9.2, there are three additional attributes for the FINFO function. They are:
File Size(bytes)
Create Time
Last Modified
Create Time
Last Modified
The sample code on the Full Code tab illustrates how to use the FINFO function within a macro to retrieve the values of these new attributes.
A non-macro technique is illustrated on the Full Code tab as well.
The create date is not stored with a file on UNIX. Therefore, the CRDATE variable that is within the code on the Full Code tab is missing on UNIX.
