Chapter 8Chapter 8Managing shared folder & data storage

Introduction Introduction Program codes and other data is

saved in your hard disk as a file.Every OS has its own way to

organize these files .Windows XP have 3 basic

divisions for the data/program:◦Files◦Folders◦Drives

File File A collection of information that

you create while you work on a computer.

Files are made up of the file name and extensions. Ex: file3.doc

‘.doc’ is recognized as an extension for Microsoft word document and OS will use the application to open the file.

Folder Folder You can store a file in a folder

and one folder can be placed in another folder creating subfolders.

Helps you to organize computer files into groups.

Windows XP stores its important files in Windows folder usually found in C drive.

Drives Drives Files and folders are stored on

drives & it holds a large amount of data and programs.

Available drives:◦Hard drive◦Floppy drive◦Flash drive◦CD ROM drive

Windows XP Files & Folders Windows XP Files & Folders sharingsharing

Multiple computers connected together with LAN, makes its possible for file & folder sharing.

Computer need to be configured to share files & folders enabling user to copy/read the shared files from another location via your local computer.

One can only access sharing folders and files if they have appropriate permissions.

Windows XP has a file sharing user interface for enabling simple files & folders sharing.

NTFS allows for more control over shared folders & files.

Simple File Sharing Simple File Sharing By default its always turned ‘on’ on Win

XP Pro computers that are joined to workgroup.

For those that are joined to domain only uses the classic file sharing and security interface.

If its turned ‘off’, you will have more control over the permissions to individual users.

When you turn ‘off’ the simple file sharing, the Shared Document feature is not turned off!!!

Level of access to shared Level of access to shared files & foldersfiles & folders

Windows XP Pro provides 5 levels of access with Level 1 being the most secure & Level 5 the least secure & allows public to view & change the data.

Level 1Level 1Can be applied to ‘My Documents’

folder & no body else can open/read any file or folder contained in My Documents folder.

Not even the administrator account can open it.

All subfolders that are in that folder & marked as private remains as private unless you change the parent folder permissions.

Level 2Level 2Owner of the files/folders as well as

the administrator has the permission to read & write & others who is not involved in the creation of that file/folder can’t access.

It is default permission for each user’s My Documents folder on Win XP Pro.

Level 3Level 3Files & folders that are shared

locally on a particular Win XP Pro machine by placing them in ‘shared documents’ folder of Win XP.

Can be read/modified & deleted by local computer administrators.

Other restricted users can only view & read files.

Simple File Sharing Access Simple File Sharing Access level Rightslevel Rights

Level 4 & 5 (sharing over the Level 4 & 5 (sharing over the network)network)Level 4Everybody has read permission but can

only write to it if special permission is given.

All local users including the guest can read the files but cannot modify the content over the network.

Level 5It is not a secure access level & should

be avoided unless necessary.Allows any user(local & remote) to

read/write /change or delete a file in the folder, even guest account holder!

Files & folder sharing Files & folder sharing guidelinesguidelines

Advisable to only share folders over the network that users on the other computers must access.

Do not share system files & important Windows folder.

Do not share C: drive as whole where your OS is installed.

Read only devices like CD ROM shared at access level 4 & 5 only.

Disk Mapping in Win XP Disk Mapping in Win XP ProProFiles & folders in a network drive

does not exist in the local machine but another computer which is connected via network.

Network drive can be assigned and accessed by drive name & letters as local hard disk drives.

Disk Mapping in Win XP Disk Mapping in Win XP ProPro

Mounted drivesMounted drivesIs a drive that is mapped to an empty

folder on a volume that uses the NTFS file system.

It functions as the same way as other drives, but they are assigned drive paths instead of drive letters.

Advantage over mapped network? – mounted drives are not subject to the 26 drive letter limit for local drives.◦ Makes data more accessible & better flexibility◦ Provide additional disk space for your

temporary files
