KwikNet Virtual File System

VFS File Access Rights

User access to files within the KwikNet Virtual File System is governed by the KwikNet

Administration Interface as described in Appendix D. The access rules are the same for

all file systems.

Each user is identified with a user name and password and is given specific access rights.

Each user can also be assigned a base directory with the user's access restricted to only

those files contained within that base directory and its subdirectories.

The definitions of your KwikNet users and their file access rights can have a significant

impact on your Virtual File System. For example, if you declare that a user has base

directory E:\userbase but create a Virtual File System with a volume base of \vfsroot,

that user will never be able to access any virtual files. The reason is simple. All virtual

files will have names like

\vfsroot\anyfile but the user can only access files with

names of the form

E:\userbase\anyfile.

If a user must be allowed access to both virtual files and real files, then the Virtual File

System volume base must, at the very least, match all or part of the user's base directory.

For example, if you declare that a user has base directory E:\userbase and create a

Virtual File System with a volume base of E:\, then that user will be able to access all

virtual or real files of the form E:\userbase\anyfile.
