FV File Explorer

The app is nice, but i thought that this app can copy or move files from internal to external storage but nothing can do, even though it can move files from SD to phone but I don't prefer that. I have tried my best to move files but It just shows me "permission denied, please enable root explorer in setting" but it has no feature to direct me on that setting. Please Developer help me to solve this problem, I really need this and thats why I installed this app wishing that can solve my problem.

GREAT App does everything that the others do maybe a little more even and I like it it's easy to use and it doesn't have any problems with USB ports and all that plug in your cupboard hanging to your computer or phone or anyting works really good I'm going to try it out again I like to before I want to try it out again and it's fast

I downloaded it thinking it would have a "rename" feature in its image browser (not file browser as is always the occasion) but was hugely disappointed. Such a fine FM but not for me. Thanks for the app, however. MIXplorer and X-plore seem to be the only FMs with this feature but they lack the design like yours which I love.
