Is there a solution to different programs using the same file extensions? In
my case specifically, I can’t install Apple’s QuickTime because it uses a file
extension QTX which is also used by Quicken 2011 program. Google searches come
up essentially empty. I’m running Windows 7 Pro.
In this excerpt from
Answercast #96 I look at some problems that can arise when different
programs try and share a file extension – and easy steps that allow you to use
Program file extensions
The very short answer is “no” – but a part of your question concerns me a little bit. You should be able to install all the programs you want.
In other words – a program should not fail to install because some other program which uses an extension that your first program uses happens to be on the machine. Everything should install just fine.
Default program to open file
The conflict arises when you try and double click on a file to open it. In fact, that’s pretty much the only time the conflict really happens.
What you end up with typically is that the last program to be installed is usually the program that then owns that file extension.
So for example, in the case of .qtx, if you have Quicken installed and you then install QuickTime – it’s very possible that when you double click on a .qtx file (regardless of where it came from) it will be QuickTime that tries to open it. If it’s a Quicken file, that of course that will fail.
The thing to do in a case like that is to simply right-click on the file and select “open with”. That will allow you to select another program to open that file with. It’s just a one-time thing (and you’ll need to do it every time for the files that have that extension that’s in conflict) but it does allow you to open .qtx files, or any file for that matter, with a program other than the one that has this default association.
Conflicting file extensions
So, ultimately there really is no way to solve it. Different programs simply often use the same file extensions.
There’s no central authority. There’s no central repository for these kinds of things. Programs choose what they choose. They try and stay out of each other’s way but obviously that doesn’t always happen.
So, the only thing you can do is choose the default association to be the one, perhaps, that you use the most and use this “open with” technique to open those files in another program when you need to.
