Program to change JPG to JPEG

[Greg12]

I need a program to convert JPG to JPEG.

You don't. They are the same thing... just some programs name them with the 'e' others don't. You can just rename the extension back and forth freely without hurting the file.
Just like .mpg and .mpeg are the same!

Thats right, you could even rename it as an mpg but still be able to open it with an image editor. The extension in windows only serves to tell windows what application to open the file with. So jpeg's are associated with certain applications, like IE, and most images editors etc... If you rename a jpg to say, mpg you can still open it by holding shift and right clicking on the file and choosing the "open with" option in the menu. You can then select the applicatin to open the file with.
BTW, you do have to hold down shift when you right click, the option is not there in the standard right click menu.

I know but My pictures will only show JPEG files, not JPG.

I tried working with file types menu under the "folder-tools"

Wanna know the fastest way to rename all *.jpg to *.jpeg?
Use DOS.
If the directoruy you want them renamed is "My Pictures" do this:
Start a DOS session.
type:
CD..
Then enter
Type:
CD /MYDOCU~1/MYPICT~1
Then enter
Now type:
REN *.JPG *.JPEG
Then enter.
All the .jpg's should now be .jpeg
You may need to refresh directory (F5 is the fastest way)

That's a really great methoid.
But i have many folders.

Once i get into a sub folder, how do i get back into the main folder.

CD doesn't work.

DOS command to return to the parent folder: 'CD ..'

Try downloading IrfranView the best file handler around... just search for it in yahoo... it's free, gives you a thumbnail of the file in your folders and handles all picture formats

I have a small DOS prog that can repeat any command line in every subfolder. It's called diskwide.exe , I couldn't find a link on google.com , so I can email it if you want ( 7 kb ).

That would be a handy utility, I couldnt actually think of a way to do this in DOS, like you can in Linux.

greg12, just give the command
CD /?
for the options that you can use with CD
Dont forget that you have to shorten the folder names in DOS as well. For example "My Documents" will be "MYDOCU~1", you should be able to figure it out easy enough. Anything longer than 8 characters gets shortened like this and you cant use spaces in your arguements (arguements = parameters passed to CD through command line, Eg. MYDOCU~1 is an arguement). If you get to know DOS a bit you will find that you can do a lot of common windows tasks very quickly and you can even program your own batch files which is very easy.

you can use more than 8 characters and include spaces for the arguments in a DOS Prompt under NT4 , Win2000 and WinXP. I'm not sure under Win9x/ME OS's it's been a while since I used them.

Simply use the " before and after.

Type "My Documents" includind the "

If you're completly out of Windows ( only possible with Win95/98 ) then the arguments are shortened to 8 characters.

Guys, just go to http://www.zdnet.com and check the download section for "multiren". This utility integrates with Windows Explorer. You highlight a group of files in Explorer, right click, and one of the choices is Multiple Rename. You can then change extensions, renumber files, etc.
