Batch file conversion

I have several hundred scanned images in .max format, which is a proprietary format for an application called Scansoft Paperport. I want to convert all of these into .jpg format. I know I can probly do it with an image editing application, but figured I'd try it the hard way. :)

All the files are in one folder, so I tried:

>rename *.max *.jpg

The extension on every file was changed to .jpg. I tried opening them in a couple of programs, but the format was unrecognized. I created a new folder with 4 .bmps and tried:

>rename *.bmp *.jpg

and this worked. Does anyone know of a way to solve this problem? Would installing the Paperport program help?

When you rename the file is it only doing that. WHen you rename the bmp to jpg it is still a bmp and not a jpg. You need a program to convert the actual file, not just rename it.

Many image viewer tools have batch conversion processes. LViewPro is what I use, but I think ACDSee does it too.

Thanks, I guess you can't do everything with text.
