Perhaps what I want is easily done. I failed to bring my thumbdrive to work to download program. If it is easily done without help, my appologies. Please ignore.
The original JPeg files that I downloaded were named 01, 02, 03, 04, etc, 02, 03, 05, 09, etc, and so forth. In attempting to differentiate between groups, I added a number, such as 18, and a group-letter such as (group) A, (group) B, (group) C, etc. 18 was for all the groups on a particular day.
Some days I had 34 groups or more (AH).
An index stated that 18A was (group) Betty; 18B was (group) Robert; 18C was Rich, 18D was Burt, 18E was Bernice. I want to rename the files, a few or a lot, depending, to Betty01.jpg, Betty02.jpg, Betty03, Betty04, Robert02, Robert03, Robert05, Robert09, etc.
IrfanView wants to change the number-names to 1, 2, 3, 4; 1, 2, 3, 4. I want the number-names to remain the same.
As I said before, if this is easily done on antp, please ignore.
Bless you. Rich
rename first part of filename
Copy names to Word
I don't normally ask questions before I have an idea of what I am talking about. As I said in my initial post, if the program is easily understood, please ignore 
When I float over the button marked 'Remove All,' the help indicates 'Remove All Files.' I very definitely do NOT want to remove the files!! I've been highlighting the file names, and pressing the Delete key, which seems to work properly.
Off to another tangent - is there a way to copy the names from the images and put into a (Word) document, most likely ASCII (txt) or RTF?
Bless you.

Remove means remove from the list. Else I would have labelled the button "delete" 
(note that in the description shown at the bottom of the window when hovering the button, it mentions that they are removed from the list)
It is easy to make a list of files from a command line, but to do it in windows the easiest way is to make a "list.cmd" file with notepad (for example) in which you put :
dir "%1" > list.txt
then drag & drop a folder on that .cmd file and it will generate a list.txt file with the contents of the folder (file generated in parent folder of the one you drag & drop).
if you only want names without details :
dir "%1" /b > list.txt
