Can't transfer files with filezilla

[Ferorake]

Hi guys,
I'm here asking a thing that I didn't find a solution for searching on the forum. 
The problem is the same as:
http://moodeaudio.org/forum/showthread.php?tid=2167

But the solution doesn't work for me. 
I have an external HDD perfectly working on the RPi4 with moode, and I can't transfer files to it with filezilla. I get access with pi\moodeaudio (id\pass) and port 22, but when I try to transfer files in the folder /media/, I get an error. I can transfer files from HDD to PC, but not from PC to HDD. 

Any ideas how can I solve it?

Hi Ferorake,

If I am right, Filezilla uses te FTP (File Transfer Protocol) protocol to transfer your files and .. MoOde uses SMB as a protocol to copy your files.

If you have a Windows PC, try accessing your Raspberry by entereing \\Moode in your explorer screen (Windows E)
From that screen, you can copy files to or from your Raspberry.

Ok now moode 7 integrates a parametric equalizer and I really need it, so I'm switching from Volumio again to moode, but I also need to access the external HDD connected to the rpi from the main PC. Filezilla doesn't work, I get "access denied" when I try to do something. Same destiny when I try to do "chmod 777 folder" to change permissions: Operation not permitted. 

Any help is appreciated...
