Windows 7: Default Programs - Associate a File Type or Protocol

Thanks, but that's the version I'm using. It allows for a portable install. I guess I'll fix it by reinstalling windows.

File extension isn't listed

The file extension I want to set default association for isn't listed, and checking the registry I see it is not there either. How can I add a new entry for the extension to the registry? The program in question is MetaTrader4, the extensions are .mq4 and .mqh among others.

(Have tried reinstalling with UAC turned off and with Admin privileges but it hasn't helped, also tried using compatibility wizard on the installer but again didn't help)

Hello Whitebloodcell,

According to that program's FAQ's page, MQ4 and EX4 are the only file extensions supported. MQH is not listed as being supported.

You might see if you can set the file extensions to be associated with MetaTrader EXE file by right clicking on the file and using Open With.

Hope this helps,
Shawn

Well the FAQ is mistaken in the case, have been using MetaTrader for a long time and the .mqh (header files for adding library code) have always been associated before under different operating systems, even under the same operating system when different brokers are used. (Each broker distributes their own copy of MT4, for some reason some broker's distributions associate correctly). Using 'open with' doesn't seem to do anything in regards to the association.

I thought that may not have looked correct. I'm not familiar with the program's settings, but you might check to see if it may have one to set itself as the "default program" or to be able to select the file extensions. If it doesn't, then the program may only support opening the files from within the program itself instead.

file ext

Brink,

There are a number of file extensions listed in the default program setting that show as "unknown." Some of these seem like they ought to have a program, like an excel library ought to be associated with excel.

Is unknown a legitimate association?
And is there is quick way to correct or reset to default all such ones?

Thanks.

Hello Fwin7fork, and welcome to Seven Forums.

File extensions that are listed with "unknown application" could just be a data file for a program or Windows 7 and is not actually opened by anything. If you look at the "Description" it will help give you an idea of what the file is for. Googling the file extension will also give you more detailed information about the file extension and if it normally uses a default program to open it or not.

Hope this helps,
Shawn

Dear Brink,
I accidentally changed the default program for opening a .py file (python code) to the command prompt . It will not let me change it back to python.exe! Do you have a .reg file for this? If not, what can I do?!
Thanks,
vincemoe

Hello Vincemoe, and welcome to Seven Forums.

Sorry, but no since .py is not a default file extension included with associations in Windows 7.

You might see if you may able to use "Open with" instead to either select the program or it's .exe file?

Open With - Change Default Program

Hope this helps,

Thanks for the speedy reply,
unfortunately when I go to select "Always use this program to open the selected type of file" the check box and words are grey and wont let me check it, it seems as if me selecting the command prompt to open it locked it up.
