1. A system comprising:
- a plurality of client computers;
a file server communicatively connected to the client computers and storing a plurality of computer files under a same user identifier in standard file attributes of the computer files, and storing access control data of the computer files in extended attributes of the computer files,wherein each client computer stores thereon local copies of the computer files received from the file server by extracting the access control data thereof and storing the access control data in the standard file attributes of the computer files,wherein the access control data of the computer files is provided by the client computers such that access to the computer files by the client computers is controlled by the client computers and not by the file server,wherein the file server is to;
receive a first communication from a first client computer of the client computers relating to a given computer file of the computer files;
extract the access control data from the extended attributes of the given computer file;
generate a second communication containing the access control data; and
send the second communication to a second client computer of the client computers,and wherein the second client computer is to;

Abstract
Methods, systems and computer program products are provided that may relate to controlling access to or accessing computer files over a computer network. A file server may execute on a first computer system and a client may execute on a second computer system. The client may be configured to send a first communication to the file server relating to a first computer file stored on the first computer system. The first communication may include first access control data associated with the first computer file. The file server may be configured to receive the first communication and extract the first access control data from the first communication. The file server may then store the extracted first access control data in extended attributes of the first computer file on the first computer system.
