If you only want to do a basic conversion with no extra tweaking in order to PP the tiff files in an editor, you could use dcraw.c from command line and type the file names of the images you want converted after any options. I'm assuming your raw files are from a Sony Alpha from your prevous posts (so, I'm using .arw filenames below). Just separate each raw file name with a space and you can convert multiple files unattended.

For example:

dcraw -w -T DSC00001.ARW DSC00002.ARW DSC00003.ARW

The -w switch tells it to use the as shot white balance (whatever you had it set to in the camera), and the -T switch tells it to output .tiff (it defaults to .ppm). Note that switches and filenames are case sensitive.

If you type dcraw without any other parameters, you'll see all available options. Here's the manual for them:

http://www.cybercom.net/~dcoffin/dcraw/dcraw.1.html

Note that if you're running Vista, you'll need to make sure the dcraw.c executable you use was compiled with a compiler that links in Win32 library versus an open source compiler like GCC or DJGPP, because MS imposed memory limitations in Vista. See this article for more details:

http://www.trnicely.net/misc/vista.html

You can download dcraw.c from here for many popular platforms, and you'll see a "Vista Compatible" download in the list:

If you want to use batch processing with a more sophisticated approach, I'd take a look at Bibble Pro. You can download a fully functional trial version:

If you double click on the "Organizing and Processing Images" section on the left side of this page, you'll see sections on setting up batch queues:

If you go to the page with documentation I mentioned in my last post, you'll see topics on how to setup batch queues and add images to it.

http://bibblelabs.com/learn/webhelp/

By default, it's going to start processing an image added to the queue immediately. But, you can set it up so that it doesn't work that way (so you can process them after you add them to the queue). Go to the section shown here for more details (you can use a Pause feature):

P.S.

If you go to this page, you'll see some video tutorials that may help, too. The Advanced Workflow tutorial goes into using Work Queues, Batch Queues, etc.

BTW, I'm familiar with an open soruce utility for Linux called UFRaw-Assist that makes it easy to do what you want to do. It works conjunction with Konquerer (the File Manager for the KDE desktop used by many Linux distributions), so you can simply select the files you want converted (up to 255 at a time), and it can convert them, denoise them, generate thumbnails, etc. It works in conjunction with UFRaw (an open source raw conversion program) using scripts.

It's built into the PCLinuxOS Digital Photography Edition.

So, if you ever want to try Linux, keep it in mind. It's got lots of nice tools built in for photographers, and it's free. You can easily install it in a dual boot configuration with Windows using it's built in installation utilities.
