renaming file types.........how do I do it????????

[20vision20]

Hi,this probably is very simple but I dont know how to rename file extensions and I need to know with all the different file types on the go. And does anybody know a CODEC pack which covers all the file extensions. Thank you.

you can rename a file name, but no file extension. If you do it though, the file might become unreadable or unplayable...

the possibly best codec pac is CCCP.

You can rename file extensions. I have had to do it from time to time when somebody has named a file:

hellabunna_rei_04.rar.1

because Windows XP wants to open it as a "*.1" file, or a "dot-one" file, and WinRAR (and sometimes even 7-Zip) are confused by the file name, too. So what I have to do in those instances is this:

1. In Windows Explorer (i.e. the default file navigator), go to the folder where the file you want to rename is located.
2. Click on "Tools" on the top menu.
3. Click on "Folder Options" in the "Tools" drop-down menu.
4. Click on the "View" tab in the "Folder Options" window.
5. Uncheck the box that says "Hide extensions for known file types." (It is checked by default in Windows XP.)
6. Click "Apply" (just to be safe) and then click on "OK."
7. You should now be able to see the full filename for all of the files in that folder.
8. Rename the file you want to rename. If you want it to go from being rei04.rar.1 to being rei04.rar, you need to type in:
   

   rei04.rar

   You can't just type in "rei04" and hit enter or else Windows won't know what to do with it!
9. When you're done, if you would like to, you can reverse the changes we have made by re-checking the "Hide extensions for known file types" box and re-clicking on "Apply" and "OK."

This is how I have renamed file extensions in the past. If this is not what we're talking about when we say "rename file extensions," then just ignore what I said. >_>

Another thing to mention:

Renaming a file extension DOES NOT FUNDAMENTALLY CHANGE THE FILE!

A file extension is just a call name (if you will), a clue to the operating system as to how to best approach opening or launching that particular file. For example, if I go into avidemux and create a new avi file, I can name it three different ways:

testvideo
testvideo.avi
testvideo.mpg

All three files are truly an avi file! But they are temporarily perceived as a data fragment, an avi, and an mpeg, respectively.

If what you were talking about in the first post was really THIS ...

I want to know how to convert an .mp3 into a .wav.
I want to know how to convert an .avi into an .mkv.
I want to know how to convert something encoded in DivX to something encoded in WMV9.

... then the answer is not what I posted above, and is instead this:
You need to get some software. Because what you're then talking about is converting file types (rather than file extensions), and that's a little more heavy-duty. Before I write any more, I'll wait for confirmation as to what, exactly, it is that you were hoping to do.

files with 'part no' at the end

hi there. ILLUMINATUS has the habit of putting part numbers at the end of files,consequently the media player will treat this as the file type and wont play it,it wont recognise it.
EXAMPLE:http://rapidshare.com/files/14001326...nozaki.avi.001

How can this be rectified. Thanks
