Some of the commonly asked questions about data sharing in windows are answered here.

You can share folders in Windows 7 Operating Systems.

Sharing Data

  1. Select the required folder. For example, the Data folder available in the default application folder (C:\Program Files\TallyPrime).
  2. Right-click and select Properties.
  3. The Data Properties window opens.
  4. Click Sharing tab.
  5. Click Advanced Sharing.
  6. The Advanced Sharing window opens and check the option Share this folder.
  7. Click Permissions.
  8. Permission for Data window opens.
  9. Select the group or user name from the Group or user names list under Share Permissions.
  10. Set the required permission for the selected Group or user names by checking Allow or Deny various accesses displayed:
  11. Click OK.
  12. The Advanced Sharing window appears.
  13. Click OK to share the selected folder.
  14. In the Data Properties window click Close.
  15. On clicking the data folder in explorer window the detailed information related to the folder appears.

Note: Click Add to include groups or users to the list of Groups or user names.

Security Settings

In order to secure a computer and its resources, you must consider the rights that users will have. You can secure a computer or multiple computers by granting users or groups with specific permissions. You can help secure a file or folder, by assigning permissions to allow users or groups to perform specific actions.

  1. Right-click the folder, and select Properties.
  2. The Data Properties window opens.
  3. Click Security tab.
  4. Select the required Group/User Name from the list of Group or user names and click OK.
  5. In case, you want to change permissions for the selected Group/User Name, click Edit.
  6. Click Add.
  7. Click Check Names to confirm the availability of the object name.
  8. Click OK.
  9. Permissions for Data window appears listing the newly added object.
  10. Set the Permissions.
  11. Click Apply.
  12. Click OK to set the Security for a selected folder.

You can share TallyPrime data folder in Windows 8.

  1. Navigate to the data folder and double-click it.
  2. Click the Share tab, and click Specific People.
  3. In the file sharing window that opens, enter the name of the user and click Add.
  4. Select the level of access, usually for Tally, the data folder has to be given Read/Write access.

  6. Click Done.
  7. Click Done.

SMB Stands for “Server Message Block.” SMB is a network protocol used by Windows-based computers that allows systems within the same network to share files. It allows computers connected to the same network or domain to access files from other local computers as easily as if they were on the computer’s local hard drive.

Not only does SMB allow computers to share files, but it also enables computers to share printers and even serial ports from other computers within the network. For example, a computer connected to a Windows network could print a document on a printer connected to another computer on the network, as long as both machines support the SMB protocol.

Though SMB was originally developed for Windows, it can also be used by other platforms, including Unix and OS X, using a software implementation called Samba. By using Samba instructions, Mac, Windows, and Unix computers can share the same files, folders, and printers.

SMB Versions

There are several different versions of SMB used by Windows operating systems:

  • CIFS – The ancient version of SMB that was part of Microsoft Windows NT 4.0 in 1996. SMB1 supersedes this version.
  • SMB 1.0 (or SMB1) – The version used in Windows 2000, Windows XP, Windows Server 2003 and Windows Server 2003 R2
  • SMB 2.1 (or SMB2.1) – The version used in Windows 7
  • SMB 3.0 (or SMB3) – The version used in Windows 8 and Windows Server 2012

SMB Negotiated Version

Here’s a table to help you understand what version you will end up using, depending on what Windows version is running as the SMB client and what version of Windows is running as the SMB server:

      • SMB2 durability
  2. From SMB 2.0 to SMB 2.1
    • File leasing improvements
    • Large MTU support

How does SMB work?

The diagram shows the way in which SMB works. Clients connect to servers using TCP/IP. Servers make file systems and other resources (printers, mailslots, named pipes, APIs) available to clients on the network. Client computers may have their own hard disks, but they also want access to the shared file systems and printers on the servers.

Clients connect to servers using TCP/IP (protocol). Once they have established a connection, clients can then send commands (SMBs) to the server that allow them to access shares, open files, read and write files, and generally do all the sort of things that you want to do with a file system. However, in the case of SMB, these things are done over the network.

How SMB impacts performance?

The following table will explain how SMB creates Impact on Performance. The version of SMB used for file sharing is determined during the SMB session negotiation. If both the client and server support SMB 2.0, then SMB 2.0 is selected during the initial negotiation. Otherwise, SMB 1.0 used for preserving backwards compatibility.

Below test was conducted to check the effect on performance.



SMB Negotiated Version

Effect on performance

Win XP

Win 7/win 2008 server


No effect

Win 7, Win 2008 server, win xp

Win XP


No effect

Win 7, winxp

Win 2008 server/win 7


Performance effected when first communication is between smb2 to smb2.

Performance not effected when first communication is between smb1 and smb1.

Performance Tests

Test 1: Test using Notepad

Testing was done by creating a notepad in the shared folder on Win 2008 server. Here the communication happens through smb2 protocol. This can be observed using the Microsoft Network Monitor. (See the highlighted line).

After creating the notepad from Windows 7 try to delete the same from Win XP machine immediately(less than few seconds). On trying to delete, system prompts error message as shown below.

The same can also be observed using the Network monitor, where it shows a Sharing Violation. (See the highlighted line).


  1. Client (Windows 7) sends Request to server to Create File via SMB2 (check in Fig 1)
  2. Server Responses to allow creation for client via SMB2
  3. After Creation, Client (windows 7) sends request to close SMB2 for the new file created. To sends this request there is a time delay.
  4. During this delay, if another request comes from SMB1 for accessing the same file then sharing violation error shown. If it is same version of SMB, then able to access the file.

When higher version named pipe is not closed and if request comes from lower version then sharing violation occurs. When lower version client is continuously attempting to access the file then sharing violation happens multiple times. This ultimately impacts the performance of client.

Test 2: Select Company > Display Company Login Screen in Tally.

Testing was done by sharing Tally data folder on win 2008 server. Tally application was opened on window 7 and company was selected to display the Login Screen. During this process the SMB2 protocol is used to communicate with the windows server 2008 machine.

Then the same data was accessed by WinXP via SMB Protocol. From the Win XP client, to display the Login screen of the same Company, it is taking time.

In the Network Monitor, it is continuously showing sharing violation in TAccess.tsf file.


  1. Client (Windows 7) sends Request to server to Create TAccess.tsf File via SMB2
  2. Server Responses to allow creation for client via SMB2
  3. After Creation, Client (windows 7) sends request to close SMB2 for TAccess.tsf file. To sends this request there is a time delay.
  4. During this delay time, Windows XP sends request to server for creation of TAccess.tsf file. Since SMB2 namedpipe is not closed for TAccess.tsf file in Windows 7 client, it is showing sharing violation in WinXP client.

Tally Application in WinXP client will wait until it gains access to the TAccess.tsf file. This wait time impacts performance.


From the tests, we can conclude that in a sharing environment, the performance will be impacted when data server is in higher SMB version and Clients are in both higher and lower SMB Versions.


Option 1

  • Data Server – SMB1 Version OS
  • Clients – (SMB 1 or higher Version OS)
  • As Data server is in SMB1, communication will happen in SMB1 only.

Option 2

  • Data Server – SMB2 Version OS
  • Clients – (SMB 2 or higher Version OS)
  • As Data Server is in SMB2, Communication will happen in SMB2 Only.

Option 3

  • Data Server – SMB3 Version OS
  • Clients – (SMB 3 or higher Version OS)
  • As Data Server is in SMB3, Communication will happen in SMB3 Only.
