How can I rename all .jpgs in a folder so that they all have s before the extension?

i.e. file1.jpg becomes file1s.jpg etc. It can be done with DOS RENAME but any suggestion that works is okay it doesn't have to be a DOS answer.

Yeah, the DOS RENAME command is probably the most simple. My DOS days, like most people's, are long gone, but try:

RENAME %26lt;space%26gt;*.JPG%26lt;space%26gt;*S.JPG.

Make sure your in the right folder first of course: DIR%26lt;space%26gt;*.jpg will list your JPG files.

Also a backup of your files to another folder before you start messing around with the filenames is always a good idea!
Go to 'Edit' in toolbar, choose 'select all', which will highlight all the files in your folder, then right click on your mouse and select 'Rename', key in your preferred file name, and all files highlighted will be automatically renamed.
You don't even need DOS Rename to change the file name. Highlight the file name prior to the extension leaving the ,jpg and type in what you want or want to add. Windows doesn't care what you name it just so long as you don't change the extension. If you need to do a lot of jpg's as a batch then try Irfanview.
