File Manager for Android HTC One of the frustrating things about HTC is that i cannot manage my files which have been downloaded. On the market place there are some apps which allow you to do this such as:


Astro File manager
eFile
Root Explorer


If i install a file explorer app, will that invalidate my warranty with HTC or android?
No, you won't invalidate your warranty.*  Keep in mind that Root Explorer requires root, though, and rooting will invalidate your warranty.  I personally love Root Explorer, so I recommend the non-root version: Explorer.

* I haven't read your warranty, but I've never heard of a condition that bizarre. This is not legal advice; I am not a lawyer.
