Changing the "open with"

iMythD · Jan 1, 2011

Okay, today i went to open a .CLASS and .JAVA file. They didnt have a program associated with them, so I opened them with Notepad. Now they all open with Notepad, and I cant use them with the program that I needed them too. The files were never linked to a program, which is why when i opened them up i had to select what to open them up with, can someone PLEASE help?

basically, im asking, how do i make the files not open with anything? (you know when you make a .file or something and its just a white page?)

Right click on the file, Properties then look for "Opens With:" then select change, then find the right program.

You should tell me what OS you're using earlier -.-
Anyways, try this:
Press the start button, and type "regedit" on the search box and press enter.

After that, a window should pop-up. Press Ctrl+F after that and type in .class and press find.

After awhile, it should found the .class extension.

On the right path, right click on the "(Default)" and choose delete. After deleting it, the .class should be unassociated with any program already.

Note

o the same for the other extensions you want to be unassociated with any program.

If after you deleted the registry keys and it didn't work, try restart your computer and check again.
