I am currently trying to transfer my files from mega to terabox in my mobile. Is it possible to do so? If it is possible how? Everytime I am trying to share from mega it is show a .txt file rather than pdf or epub file I selected.
a little late but if you're still interested...
airexplorer can do it.

the windows version can do it for sure, but I've never tried the android version. to check therefore.
the free windows version has very few limitations and is perfectly usable, but for the android version, the same, never try it so I don't know.
