In Excel 2003 if you go to “Tools > Share Workbook” and check off “Allow change by more than one user at the same time.” They can both open it with read/write permissions. You also might want to activate merging so they do not overwrite each other.

With NTFS security, I have found you cannot just give access rights successfully at the file level. If done at the file level, our users would be able to open the file, if they had the folder rights to ‘write’ then they could save their changes, but now the resulting file would have the same ACL as the folder it’s in. Since the ‘modified’ file is seen by NTFS as a ‘new’ file.

How many wish we could force MS to use the Novell model for access control?

Once this has been done just add the users to that group an hey presto they have read/write permissions to any file contained with in the folder.

Also good as if you need any one elso to have access just add then to the new group making permission handling easy to control

You want 2 users to have access to the file, with the ability to modify the file.

You can either give the user group (the group that the 2 users belong to) or the individual users access to the file, by adding them to the list. Then make sure that Modify, Read&Execute, Read, Write are ticked.

But generally when you set up the share, you set the permissions at the folder/directory level, as NTFS automatically gives the child files & folders (the files and folders that live in the share.) the same permissions.

This is where the idea of parent/child(ren) come into play. Consider this…

C Drive
|
|-File1.txt
|
|-Folder1
|
|-Folder 2
|
|-File2.txt
|
|-Folder3
|
|-Folder4

“C Drive” is the parent of everything there. File1.txt, Folder1, Folder2 are children of the parent “C Drive”. And File2.txt, Folder3, Folder4 are children of the parent Folder2.

Just as living things, children can have become parents, so a child in a structure like that can become parents.

Also this structure can also be called trees.
