MAINTAINING THE SNAP PAC R-SERIES CONTROLLER
SNAP PAC R-Series Controller User’s Guide

Storing and Accessing Data or Files
When inserted into the controller and accessed from a PC using FTP or PAC Control, the card
appears as a directory in the controller’s file system named:
sdcard0
Just like a PC might
show a thumb drive as a directory named Removable Disk (E:), for example, the controller
shows the card as a directory named sdcard0.
IMPORTANT: Do NOT try to create this directory. When you look at the card in the controller, the
card appears as a directory named sdcard0. When you look at the card in a card reader attached
to your PC, you see the card reader’s directory instead. When the card is in a card reader, you are
already in the root of the card (that is, you are already inside the sdcard0 directory).
For example, suppose you are looking at a microSD card in a SNAP PAC controller with IP
address 10.192.54.241. You can see that this controller has three files in its regular file
system, plus the microSD card:
