Fileinfo in golang gives Name, time modified, size, etc. I need to get particular File's description(eg: Product name, Original filname, etc.) using golang in windows.
You can use the w32 library for Win32 API calls from Go. No CGo needed.
Here is an example of how you can retrieve all file information through GetFileVersionInfo and VerQueryValue:
package main
import (
"fmt"
"github.com/gonutz/w32/v2"
)
func main() {
const path = `C:\some file`
size := w32.GetFileVersionInfoSize(path)
if size <= 0 {
panic("GetFileVersionInfoSize failed")
}
info := make([]byte, size)
ok := w32.GetFileVersionInfo(path, info)
if !ok {
panic("GetFileVersionInfo failed")
}
fixed, ok := w32.VerQueryValueRoot(info)
if !ok {
panic("VerQueryValueRoot failed")
}
version := fixed.FileVersion()
fmt.Printf(
"file version: %d.%d.%d.%d\n",
version&0xFFFF000000000000>>48,
version&0x0000FFFF00000000>>32,
version&0x00000000FFFF0000>>16,
version&0x000000000000FFFF>>0,
)
translations, ok := w32.VerQueryValueTranslations(info)
if !ok {
panic("VerQueryValueTranslations failed")
}
if len(translations) == 0 {
panic("no translation found")
}
fmt.Println("translations:", translations)
t := translations[0]
// w32.CompanyName simply translates to "CompanyName"
company, ok := w32.VerQueryValueString(info, t, w32.CompanyName)
if !ok {
panic("cannot get company name")
}
fmt.Println("company:", company)
}
