Need help with transferring files in Mobox

[RedDragonTix]

Hi! I'm new to Mobox and I have no clue how do you transfer files from android to mobox? I've heard D:/ drive is in Downloads directory but there is nothing in D: I have files in Downloads but it doesn't show in D: I have WOW64 build

I also get an error with mkdir: cannot create directory '/sdcard': Permission Denied so that explains why doesn't show in D:? I did allowed storage permission in the Termux's settings! Mobux works fine though

any ideas? OS: Android 11 Phone: Samsung Galaxy A70
