Hi, I have tested this behaviour on both a N1 and the emulator. Could anyone tell me if that is a problem? I don't think it would go forever. How can I avoid the recursive code going forever? What is happening? If you use any file browser/manager and starting going into /sys/devices/w1 bus master/subsystem/devices/w1 bus master/subsystem it will go inner forever, repeating that pattern devices/w1 bus master/subsystem/ forever. So when I run a recursive search it keeps going deeper and deeper and seems never to finish. What is happening, how to avoid this behaviour? I tried different file manager and they all seems to be going forever into these folders, although when I do a search through Astro it doesn't seem to get stuck with this loop (It seems to ignore the /sys folder, but I am not sure if this happens also in any other folder). Regards.
