Shareable Entities
• Entire disk– Independently
• Directories– Independently
• Files– Within the context of the directory in
which they reside

The Concept of Share-Name
• Each resource (directory) is shared using a name
• The name can be the same name as the original resource (directory) itself

• Limiting access to selected files• Case example for limiting file sharing• Steps for hiding the file named Rules• Demonstration on hiding the file name
Rules
![Page 24: CHAPTER Sharing of Soft Resources. Chapter Objectives Provide an overview of soft resource sharing Describe the method for placing a soft resource for.](https://reader035.fdocuments.in/reader035/viewer/2022062523/5a4d1b107f8b9ab05998e821/html5/thumbnails/24.jpg)
File Sharing Limitation in Windows Peer-to-Peer
Sharing
• Access to files cannot be individually controlled in sharing
• The lowest level of access control is limited to directories – All the files in the directory thus
become shareable automatically
![Page 25: CHAPTER Sharing of Soft Resources. Chapter Objectives Provide an overview of soft resource sharing Describe the method for placing a soft resource for.](https://reader035.fdocuments.in/reader035/viewer/2022062523/5a4d1b107f8b9ab05998e821/html5/thumbnails/25.jpg)
Limiting Access to Selected Files
• Store all the files to be shared in one or more separate directories designated specially for sharing – This is not always possible
• Hide the files in the directory that are not shared– Also assign read-only access control
to these files
![Page 26: CHAPTER Sharing of Soft Resources. Chapter Objectives Provide an overview of soft resource sharing Describe the method for placing a soft resource for.](https://reader035.fdocuments.in/reader035/viewer/2022062523/5a4d1b107f8b9ab05998e821/html5/thumbnails/26.jpg)

Module Objectives
• The multi-step process• Steps for removing the hidden file
attribute on Tariff• Steps for removing the read-only and
hidden file attributes on rules• Restoring hidden file attribute to system
files on Tariff• Demonstration of removing the read-
only and hidden file attributes
![Page 33: CHAPTER Sharing of Soft Resources. Chapter Objectives Provide an overview of soft resource sharing Describe the method for placing a soft resource for.](https://reader035.fdocuments.in/reader035/viewer/2022062523/5a4d1b107f8b9ab05998e821/html5/thumbnails/33.jpg)
A Multi-Step Process
• First, remove the hidden attribute on all the files in the directory using the explorer view
• Select the file named Rules independently and remove the Read-only and Hidden file attributes
• Reestablish the hidden file attribute to system files

Module Objectives
• Definition of drive mapping• Mapping drives illustrated• Notes on mapping• A case example for drive mapping• Steps for mapping a drive• Demonstration of drive mapping

Drive Mapping Defined
• A resource on the network is mapped to a local drive– By assigning a drive letter
• A logical drive is thus temporarily created at the local peer corresponding to that network resource

Notes on Mapping
• Resources that could be mapped:– Drives– Directories
• Different procedures can be followed for drive mapping
• A mapped drive can be disconnected as well
