Manage files using USB storage devices

Most TransPort routers are equipped with USB ports that you can use to connect Mass Storage
Devices (MSDs) such as external hard drives or flash-memory pen drives. All the files on the USB device
are listed under the USB Directory Listing heading on the Administration > File Management >
FLASH Directory page.
The USB storage device must be formatted using the FAT16 or FAT32 file system.
WARNING! For the TransPort WR31, the USB port is for use in a normal location only, not a
hazardous location.
When the USB storage device is first inserted into the router, the operating system looks for a file
named autoexec.bat, and if found, executes it. To execute other batch files, press the Reset button
one or more times. The batch file to execute must be called pb<n>.bat, where <n> is the number of
times the Reset button must be pressed to execute the file.
SD memory card support
Some TransPort routers are available with internal SD memory card. The drive letter assigned to this
card is s:. To access the SD memory using an FTP client, the subdirectory assigned is sdmmc. You can
use the SD card in the same way as USB MSDs. The SD card is internal and cannot be removed.
Batch control commands
Batch files can contain one of the following two control lines: ERROR_EXIT or ERROR_RUN. ERROR_
EXIT causes any commands run after that point in the file to terminate the batch file if that command
causes an error; for example, attempting to delete a file that does not exist. ERROR_RUN returns the
operation to default, which is to continue executing batch file commands.
