FTP Multiple Access File?

[pelagic]

Hi All,
I have an Excel file( Alluser.xls) and I have set this file for share by multiple users and allowed them to modify this file.
I have placed this file in a folder named Data and this folder is placed in UNIX FTP site.
Is there a way that multiple userd access this file directly from UNIX FTP site?
What currently happend now is, that user has to download to the local drive and modify and then send back to the server and this is not what I want.
I want them to access directly from the FTP site and save it from there. Are there any settings that I have to set for the FTP site such as full-access, Read, Write or Execute?

Thank you very much for your time.

Its acting as exactly what it is "FTP" if the users are on the local intranet or local LAN you can install SAMBA which will allow them to add a network drive to their system and read/write directly to the file as if it were on their PC.

However you will run into problems if more then one person is trying to write to the file at the same time........
