Photoshop :: Use Of Actions Without Opening Files

I'm a commercial photographer using PSCS2. I routinely will shoot small jobs with between 100 and 200 images. I shoot RAW 100% of the time (Canon 10D & 20D). I transfer the images from the CF cards to my computer with a card reader and then use Bridge to open them up. I rename them in Bridge and delete any obvious dogs. The rest (say 140+ images) I open in Camera RAW. I do all of the exposure, white balance, saturation and the like in Camera RAW. The only thing that I like to do in Photoshop proper is to sharpen the images with Smart Sharpen and then save the crw/cr2 files as either psd files, jpegs or both. I'll write an Action to accomplish that.

I take the 140 RAW files and I open them ALL AT ONCE in Photoshop. Once they're open I can use the Automate feature and run the Action on all of the open files. But to open this many files takes about an hour to an hour and a half! My computer I should mention is a 64 bit AMD with 2 gig of memeory so it's no dog.

Can I run the action on the files in a folder WITHOUT OPENING THEM?
