# Number of Characters in UNC Path

The standard default maximum length for a UNC path in the File Output Port is 260 characters for Windows API.

A local path is structured as follows:

`C:\Lasernet\Output\`

or

`\\<Local machine>\<Local path>\`

## Local Computers

For local computers, an extended-length path can be supported for a maximum total path length of 32,767 characters. To specify an extended-length path, you can use a prefix:

`\\?\C:\<Very long local path>\`

or

`\\?\<Very long local path>\`

## Shared Network Drives

To support extended-length paths for shared network drives, ensure you are using Lasernet 6.7.6, Lasernet 7.1 or above and type `\\?\UNC\<Server>\<Path>\`.
