renaming files converts from psd to jpg,downsizes file.

I am creating a genealogy book in Photoshop, using Bridge. I am on MacOS Mojave 10.14.6, using Photoshop 22.4.1 and Bridge 11.0.2.123. Batch renaming files in Bridge has converted files from psd to jpg, thus flattening all layers and downsizing from 8.5" x 11" 300mp to  .5" x .4" 300mp, and deleting original psd. I don't know where to start and may not have savvy to solve.

I would carefully check the parameters you have set in the Batch Rename dialogue.

I say this because there is an option there to change filename extensions and that may just be the cause of your issue:

I tried to rename several raw files. In fact it did rename them, as I wanted, as jpgs as requested, but the raw files are gone.

Changing filename extensions is generally a bad idea. 

If you want to convert RAW to jpg (which is entirely different to simply changing the extension)

• use the Export feature in Bridge
• or open them all in Camera Raw and save from there as jpg files
• or use the Photoshop Image Processor (Tools>Photoshop>Image Processor)

Any of the above methods will convert your RAWs to jpg (or other formats for that matter) and not just change the filename extensions.

You cannot change file types by renaming them. Those files are still PSD, even if you changed the file extension to .jpg.
