I really don't understand what you're trying to tell me.
Let's say I have a folder, in Windows, called "MainFolder". Within it I have subfolders: "Cust1Folder", "Cust2Folder",...
Let's say in HFS I have accounts for Cust1, Cust2,... and I want Cust1 to only be able to access/upload to Cust1Folder, Cust2 to only access/upload to Cust2Folder, etc.
Now, I know I can do this by adding Cust1Folder, Cust2Folder, etc. individually to HFS, and then setting permissions on each one.
I also know I can just put MainFolder in HFS and set each account's "After ~login redirect to" attribute to their appropriate subfolder. However, that doesn't stop an account from navigating up a level after login and seeing all the other accounts' folders.
It would be nice if HFS had the concept of a "root folder" per account, like FTP - i.e. a way to limit an account to navigating no higher than a particular folder in a hierarchy.
Does anything like that exist? Could it be added? Would anyone be interested in adding it (for a fee)?
