550 Permission denied

[Flavio61]

Hi all,
I'm new to using FileZilla and FTP servers in general, so I apologize if my question may be trivial.
On my test machine I installed and configured Filezilla Server. Using Filezilla Client I access the server and I can both create and delete files in the user's folder. The problem arises when I try to access the Filezilla server with our accounting management software that is simply supposed to upload some files to the server. When from our software I try to send the files to the Filezilla server, the connection is successful but then I have a 550 Permission Denied error and I can not send the files to the server. The full log is this: "2023-09-14T16:40:28.237Z << [FTP Session 19 192.168.100.74] 220-FileZilla Server 1.7.3

The whole system (client and server) runs on a single PC so files transfers take place on the internal network, they do not run outside our network. The firewall and antivirus are disabled. All the permission on Filezilla folders and users folders are set correctly (complete control to the user and to Everyone). Thanks for any help.

All the permission on Filezilla folders and users folders are set correctly (complete control to the user and to Everyone).

And the permissions in FileZilla Server, for the mentioned user account? They need to be set to "Read + Write", too, for enabling uploading.

I think I put them right, also because I guess if they weren't right it shouldn't work with Filezilla Client either.

Does the Windows user account the FileZilla Server service runs under (SYSTEM by default) have permission to access the target directory?

[Flavio61]

Yes, I think that permissions are ok.

The virtual path in the picture is "/FlavioNB/FilezillaServer", but your client is trying to upload the file in "/", the root, which is not associated with any native path and is thus non-writable.
