Ok so I reformatted my computer. Now all my pictures arent labeled outright with a .jpg or .bmp. Anyhow, I used to be able to just change the file name to the extention I wanted and it would actually change the properties as well. Also, I used to be able to see the extention when I "renamed" and it was highlighted in blue.

Now, it just makes the extention part of the name (i.e. picture.jpg.bmp) and it is still in its previous format.

My question is: How do you change a file by renaming it and be able to see the extention when it is highlighted.

Any help is appreciated.
