Thanks for reply. I am aware of what you said. What I need is, to assign write permissions for user 'A' to copy or remove data from that folder. Rest of the users shouldn't have write permissions. This is to assign permissions for user 'A' to copy or delete data to a folder which is the home folder for ftp. To enable user 'A' to write data to that folder, without interference of the admin. At the same time, rest of the users should only have read permission. Hope you got my clutch.
