Are you looking for a Android root explorer but don’t want to spend money on it, recently because of Skype problem I was looking for a root explorer but all good ones were paid, after a few app trials I found out a application named Super Manager which is available for free download from Android Market and it did the job for me. Its a feature rich fully functional application utility and is free.
