Changing Multiple File extensions in one go

Hello,

This is my first time here so I hope I am going to do this correctly. I don't know how, but some time ago, I found that my collection of music in my PC had the file extension changed.

I have a Toshiba Satelite Pro L20 with M/S XP Service pack 2.. and I have 1988 songs with a dodgy extension

In the my folders, the tab for " hide file extension" is NOT clicked and I can change the file extension of the songs, one by one... but with nearly 2000 to do.. the thought is killing me.

The extension I have right now is .MP3^ and I want them all to be .MP3 without that half hat that I have no idea what it is for

Some of the songs are .WMA^ but they are also wearing the same ^ hat...

What do i have to do so that i can change the extensions in one go on all 1988 songs, I tried from one of your other questions and used the ren command thing, but i must be doing someting wrong.. and while i have a certain understanding of computers, when it asks me for paths and directories and the like, it makes me want to run away... lol

Pleaseeeeeeeee help..

 

Get a file rename utility, Rename Master is a good one.

 

Thanks for that Stanley, I have downloaded the program, but dont have a clue what I am supposed to do with it.. Is there an easier way.??. Baby language would be good..

 

Find where the files are and then use the replace command to replace the extension with mp3. Here's a screen shot:

 

Sorry, I don't have a clue what that program is about. Thanks for your help anyway.. xx
