How to ouput ftype path only to .txt

Question

I have a known filetype (blendfile) and I want to write the associated application path into a .txt file (in the same folder as the batch script).

So for example, for a .txt file I'm using: ftype blendfile >> "%~dp1BlenderPath.txt"

Which gives me an output of: blendfile="C:\Program Files\Blender Foundation\Blender 2.83\blender.exe" "%1"

But I only want the "C:\Program Files\Blender Foundation\Blender 2.83\blender.exe" part written into the text file. How do I achieve this?

(EDIT: Edited question to be specific to the filetype path I was looking for)

Answer 1

For the blendfile, try:

@echo off
for /f tokens^=1^,2delims^=^=^" %%i in ('ftype blendfile') do echo "%%~j"

ftype stores various formats, so this particular item will not work for all ftype entries.

So to get all of the ftype values, you need a bit of a hack. For the amount of time I have, this is the best I can do:

@echo off
setlocal enabledelayedexpansion
(for /f tokens^=1^,2*delims^=^=^/^" %%i in ('ftype') do (
   set "str=%%~j"
   set "str=!str: %%1=!"
   set  str="!str!"
   set  "str=!str: "="!"
   echo !str!
  )
)>"%~dp1BlenderPath.txt"
