Retrieving File Creation Date in Windows using Go

Question: How can I access the creation date of a file in a Windows system using the Go programming language?

Answer: To retrieve the creation date of a file in Windows using Go, you can utilize the os.File's Sys method to obtain the system-specific data structure, specifically, the Win32FileAttributeData for Windows systems. The Win32FileAttributeData structure contains, among other fields, the CreationTime, which represents the creation timestamp of the file.

To demonstrate this approach:

import (
    "os"
    "syscall"
    "time"
)

func GetFileCreationTime(path string) (time.Time, error) {
    fileInfo, err := os.Stat(path)
    if err != nil {
        return time.Time{}, err
    }

    // Verify that the file information is compatible with Windows
    sysFileInfo, isWindows := fileInfo.Sys().(*syscall.Win32FileAttributeData)
    if !isWindows {
        return time.Time{}, nil
    }

    // Convert the nanosecond timestamp to a `time.Time` object
    return time.Unix(0, sysFileInfo.CreationTime.Nanoseconds()), nil
}

Example Usage:

creationTime, err := GetFileCreationTime("./myfile.txt")
if err != nil {
    // Handle file opening error
}
fmt.Println("File creation time:", creationTime)

By utilizing this approach, you can easily retrieve the creation date of a file in Windows systems using the Go programming language.
