File MIME types

Recommended Posts

I was looking to find the MIME type of a file using AutoIt and found a function to do it but it only detects the 26 hardcoded, test, MIME types and returns 0 if the file is not one of the few hardcoded MIME's... So I decided to throw a function together... It detects 249 MIME types via the files extention. The thing is it dedects only by the extention; and not by actually checking the file.

True MIME Finder: Supports 26 MIME Types

; sample usage

$file = "c:\file path\file.txt"
$mime_type = __GetMIMEByCode($file)
MsgBox(0, "MIME Type:", $mime_type)

; the function

Func __GetMIMEByCode($f_file)
    $f_call = DllCall("urlmon.dll", "long", "FindMimeFromData", _
                "ptr", 0, _
                "wstr", $f_file, _
                "ptr", 0, _
                "DWORD", 0, _
                "ptr", 0, _
                "DWORD", 1, _
                "ptr*", 0, _
                "DWORD", 0)
    If @error Then Return 0
    $f_mime = DllStructGetData(DllStructCreate("wchar[" & _WinAPI_StringLenW($f_call[7]) & "]", $f_call[7]), 1)
    Return $f_mime
EndFunc

Determine MIME By Extension: Supports 249 MIME Types

;sample usage

$file = "c:\file path\filename.txt"
$mime_type = __GetMIMEByExtention($file)
MsgBox(0, "MIME Type:", $mime_type)

; the function

Func __GetMIMEByExtention($f_file)
    Local $f_extension = StringSplit($f_file, ".")
    Switch '.' & $f_extension[$f_extension[0]]

You'd be better off creating a script that reads the file the way FindMimeFromData does and use that information to determine the mime type. FindMimeFromData reads the first (approximately) 256 bytes of a file and looks for a file signature in there to determine what the mime type is. You can find a list of mime type signatures to look for here. You can do a FileRead of the first 256 bytes by opening the file in binary mode and specifying the bytes to read. You can read how FindMimeFromData works here if you're not familiar with it.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

How to ask questions the smart way!

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Back up and restore Windows user files _Array.au3 - Modified array functions that include support for 2D arrays.  -  ColorChooser - An add-on for SciTE that pops up a color dialog so you can select and paste a color code into a script.  -  Customizable Splashscreen GUI w/Progress Bar - Create a custom "splash screen" GUI with a progress bar and custom label.  -  _FileGetProperty - Retrieve the properties of a file  -  SciTE Toolbar - A toolbar demo for use with the SciTE editor  -  GUIRegisterMsg demo - Demo script to show how to use the Windows messages to interact with controls and your GUI.  -   Latin Square password generator

There's also a command line app to do file type identification called TrID.
http://mark0.net/soft-trid-e.html
To use it, download the win32 app and the definitions.

Bonus: This can help you find the type of a file that has been renamed. If you have a file with an incorrect or missing extension, you can use TrID to find out what extension to give it so you can view/edit it.

Who else would I be?

Thanks for the information bud. I want it to find the true MIME type, not just suggested MIME from the extension like I have now... I'll look into that tool. Thanks again.
