Accessing Java Directories in Java only PI ( PO / PI7.31)

Hi Experts,

We are currently using PO system for our integration.

Earlier in PI Dual stack system we used to check the file posted in PI application server using AL11 tcode.
Could you please tell me how to check it  if the same is required to check in a single stack PI (Java only)?

Thanks
