win mpe file manager

i have copy DN3_v5_N7105_by_E-Team

from ExtSDcard1  Dir ROM

to internetSD        Dir SNote

but when after Gummy ROM success

i wipe factory reset and want to redo

then both copies is corrupted

windows file manager not able to see

can only use MPE

and it can only see Internal memory Dir SNote

but later i found it is because MPE is trying to capture the memory 

internal and external

so when exit MPE

then can copy but dun know the speed

but window is faster

but unfair as window file explorer is keep access to hp memory as prority

Another problem

is using SD reader and mouse will be disable

(black box ...)
