I have a problem. Whenever I download a Java file (Minecraft Mod) it becomes a Wordpad file and I can't use it.
A java file is a java file, nothing changes.
The problem is that you are set in the system that the file extension. Java should be opened with the program WordPad (for whatever reason).
Right-click → Open (with) → select the program with which you want to open the file…
If you use Windows:
right-click on the file
then go to properties,
search on "open with"
Select the software you want to use to edit the Java file.
No, it is and remains an ascii file. No matter what the filename extension is.
If she refused to let Windows handle her using Wordpad (or a similar program), Windows would not be able to write a java program at all.
If I remember rightly Windows, one could with a right click on such a file also "open with" select. Java should be there.
Yes, with which I do not know
