To rename your selected files and save these in another folder:
1. Start the Batch Rename command in Bridge by selecting Batch Rename from the Tools menu.
2. From the Batch Rename menu, you’ll see three sections; Destination folder, New Filenames, Options, and Preview. In the Destination Folder section, select whether you wish to rename the files in the current folder, move the files to another folder, or copy the renamed files to another folder. I recommend that you copy the files to another folder to keep the originals intact. Click the Browse button to select an existing folder to copy these renamed images to, or to even create a new folder to store these files.
3. In the New Filenames section, select Text in the first field, and in the blank field, type in the text you wish to describe each file. Click on the + to display another naming convention. In my example, I always like to follow up the first part of a filename with a date as shown in my example. Click on the + to bring up another naming field that you can choose. I always like to number my filenames sequentially, as shown here.
4. In the Options section, click on Preserve current filename in XMP Metatada, this will keep the original file name stored with other file data.
5. In the Preview section, you can see how your filename will now appear.
6. Click the Rename button when you are completed making your naming changes.
