Net shareManages shared resources. Used without parameters, net share displays information about all of the resources that are shared on the local computer.

Syntax

Remarks
To share a directory with a path that contains a space, enclose the drive and the path of the directory in quotation marks (for example, "C:\Path Name").
When you display all the shared resources on a computer, the share name of each resource, the device names or path that are associated with the resource, and a descriptive comment about the resource appear. The output is similar to the following:

Sharename Resource Remark
ADMIN$ C:\WINNT Remote Admin
C$ C:\ Default Share for Internal Use
print$ C:\WINNT\SYSTEM\SPOOL
IPC$ Remote IPC
LASER LPT1 Spooled Laser printer

As you create shares on a server, they are saved. When you stop the Server service, all shares are disconnected, but they are reconnected automatically when the computer is restarted. For more information about services, see Related Topics.
Shared resource names that end in a $ character do not appear when you browse the local computer from a remote computer. For more information, see see Related Topics.
Examples
To display information about shared resources on the local computer, type:

net share

To share a computer's C:\Data directory with the share name DataShare and include a remark, type:

net share DataShare=c:\Data /remark:"For department 123."

To stop sharing the DataShare folder you created in the previous example, type:

net share DataShare /delete

To share a computer's C:\Art Lst directory with the share name List, type:

net share list="c:\art lst"
