My guess is that the Space in 'Operating Systems' and 'Program Files' is what's killing it. You might be able to escape those somehow, but I'm not sure how to do it (it would need to be some sort of posix-compliant method).
Also, it should have forward slashes instead of backslashes, since it's being accessed from linux instead of Windows. Otherwise, the rel_path value should be able to hold a multi-level path without problems. (Unless there are problems I'm forgetting about.)
you could try
Code:
rel_path=Program\ Files/Operating\ Systems/Android
(that escapes the space characters) but I'm pretty sure that won't actually work. You can also try
Code:
rel_path=Program\040Files/Operating\040Systems/Android
(that escapes the spaces a little differently) which might work, but might not -- I really have no idea.
