I don't know of any setting in UltraEdit which results in an automatical usage of command chmod
by UltraEdit after uploading a new file to a UNIX/Linux server to set the file permission to what you would prefer for newly uploaded files.
On Unix/Linux servers it is usually possible to configure the default file permissions on a per directory (tree) base via proftpd.conf
as explained on page Configuring a <Directory>
if ProFTPD is used on the server. Maybe you have access to this file or can contact the server hoster and ask if it is possible to change the umask value for the parent directory of the directory tree you use.
It looks like there is a problem with understanding the permission rules. The security settings on FTP server control if permissions can be changed at all by a client and what are the default permissions for an uploaded file. Most FTP servers do not allow that a client with its limited account permissions modifies file permissions of files on server. Adding a setting in UE/UES for defining the permission attributes for uploaded files is a useless setting if the server does not allow a client to change the permissions of a file. And FTP servers are configured usually for preventing clients to change file permissions. If you are an administrator of the FTP server, change the default permission for uploaded files on the FTP server instead of forcing the client to change the permissions per command after every upload of a new file.
