file roller cant zip files residing in a nas server

[xoristzatziki]

I am trying to compress some files that exist in a NAS storage server (samba server)
If I try to create the compressed file in that place the message is:
Not allowed to create file (which is fals... I can create anything there)

If I try to create the compressed file in my local space the message is:
Try to copy files locally first.

I have plenty of space in both places (locally and in NAS storage).
I have free full access to NAS storage.
I have plenty of space in /tmp directory also.

I searched and someone stated that samba cant assing or read a readonly flag to files , which might be the problem.

(I think file roller, for some reason, is trying to create a readonly file there in both cases )
