Based on the Import Activity file specification input box, you may think that only three wildcards are available — year, month and day:

However, in the Salesforce Marketing Cloud Help page for Import Activities, you’ll notice that there are more listed:

%%Year%%
%%Month%%
%%Day%%
%%Hour%%
%%Minute%%
%%Second%%

So if you need some more granularity in files you’re uploading to your SFMC FTP share, yes, you can use minutes and seconds.

Don’t forget about the case-sensitivity disclaimer. Because SFMC utilizes non-Microsoft CDNs for FTP and image hosting, your file name specifications must match exactly.
