Windows File Access Control in Go

Controlling file access in Windows differs from Unix systems. Windows utilizes access control lists (ACLs) to manage permissions, comprising access control entries (ACEs) defining user and group access levels. Go's os.Chmod() provides limited file permission control on Linux, but on Windows, it's essentially ineffective.

Solution: Using the "go-acl" Package

To effectively control file access in Windows using Go, consider utilizing the "go-acl" package. This package simplifies ACL manipulation, offering a familiar Chmod() function. Its usage is straightforward:

<code class="go">import "github.com/hectane/go-acl"

err := acl.Chmod("C:\path\to\file.txt", 0755)
if err != nil {
    panic(err)
}</code>

Results: Defining File Permissions

The Chmod() function creates ACEs in the file's ACL, determining the access levels for specific entities:

• Owner: Full access (read, write, execute)
• Group: Write and execute access
• Everyone Else: Read-only access
