 The file manager may be used to access USB flash drives. When the /mnt/fl1 folder is selected the file manager will automatically perform the mount command.

+=== Accessing USB storage from a program ===
+
+{{{
+system("mount -t vfat /dev/sda1 /mnt/fl1");
+
+FILE* file = fopen("/mnt/fl1/outfile.txt", "w");
+if(file != NULL)
+{
+   fprintf(file, "Gross Weight %g\r\n", wtdata[1].grosswt);
+}
+fclose(file);
+
+system("umount /mnt/fl1");
+
+}}}
+This example will mount the flash device, write a file to it, and then unmount the device.
