Unity XT 380 equipment and firmware is 5.2.0.5.173.

I'm using it as a file (NAS) and I'm using FTP.

share name : mnd

ftp://ip address /mnd_imghome
ftp://ip address /A
ftp://ip address /B
ftp://ip address /C
ftp://ip address /D

That's normal

access ftp://ip address/ in Windows, folders exist within mnd_imghome.

ftp://ip address /mnd_imghome/mnd_imghome
ftp://ip address /mnd_imghome/A
ftp://ip address /mnd_imghome/B
ftp://ip address /mnd_imghome/C
ftp://ip address /mnd_imghome/D

So this is what it looks like.

'ftp://ip address /mnd_imghome/A'

In addition, 'ftp://ip address /A' and 'ftp://ip address /mn_imghome/A' are synced with each other, showing the same file creation and deletion.

When i connect ftp to a program like Filezilla or Windows cmd window and check it, it is displayed in a normal way.

Can you tell me how to solve this?
