Making a file (bat?) to automatically create files associations?

Hello, currently if i want to had a file extension to Windows, i have to open the new file type, select the app & tick "always open with" then go to the "Types" app to select correct icon.

This take times, especially if doing it on many computers. So is it possible with a .bat/cmd file to create these extension AND make them display the correct/unbroken icon?

Would something like this accomplish what you want? Edit File Type Association, Actions & Icon From Right-Click Menu

... If you read my message (not just the title), you'll see i mention this exact app which i use already. So i look for something else obviously. Thanks for taking time to reply though.

Oh, sorry

Something like this? batch - Programatically associate file extensions with application on Windows - Super User

Example used in Answer in above link:

Code:

Assoc .php=phpfile
Ftype phpfile="C:\Program Files (x86)\Notepad++\notepad++.exe" %1

It looks good but didn't work for me! It would set the right icon anyway.. Here's what i tried :

Assoc .gp4=gp4file
Ftype .gp4=gp4file="D:\Apps\GuitarPro5Portable\GuitarPro5Portable.exe" %1

You may think pointing to portable apps doesn't work but it does when i do manually.

Code:

Assoc .gp4=gp4file
 Ftype (.gp4=)gp4file="D:\Apps\GuitarPro5Portable\GuitarPro5Portable.exe" %1

The bold part is incorrect, does it work if you delete that bit? Or a typo?

See

Code:

Assoc .gp4=gp4file
Ftype gp4file="D:\Apps\GuitarPro5Portable\GuitarPro5Portable.exe" %1

edit: bold is hard to see, I put parenthesis around it too

It works indeed, thanks! However as i said, it doesn't fix the icon correctly

See if this works better (taken from windows - Associate a File Type with a Specific Program - Super User)

Save as .bat file

Code:

set ftypename=potato_xxx_file
set extension=.potato
set pathtoexe="C:\potato.exe"
set pathtoicon=""

if %pathtoicon%=="" set pathtoicon=%pathtoexe%,0
REG ADD HKEY_CLASSES_ROOT\%extension%\ /t REG_SZ /d %ftypename% /f
REG ADD HKLM\SOFTWARE\Classes\%ftypename%\DefaultIcon\ /t REG_SZ /d %pathtoicon% /f
ftype %ftypename%=%pathtoexe% "%%1" %%*
assoc %extension%=%ftypename%

Some hints:

ftypename - FileType name can be random but should be unique.

extension - A filename extension. Examples of filename extensions are .png, .jpeg, .exe, .dmg

pathtoexe - Full executable path.

pathtoicon - Full path to icon or executable file with selected icon. If icon path empty then default icon from exe will be used. If want use custom icon change set pathtoicon="" for example to set pathtoicon="C:\icons\potato.ico".

Works atleast in Windows 7.

Yes it works, thank you! Now i gotta make a list of all the needed extensions.. ^^

Nice :)
