XnView Software

Hi, I'm new to XnView MP and trying to organise all my images into a better filing system. I made a mistake in the naming of a few files and wonder if the very original names from the camera can be rcovered with an undo rename? It's not a disater but would like to have them all named the same. My workflow and mistake:
1: culled all unwanted images
2: organised folders into Pictures/Year/Date-Event/Date-Event-Camera File.jpeg,raw,etc ({Folder name}_{Filename})
So far all as expected.......
3: added more images to Date-Event folder and then renamed all via select all-edit-rename-{Folder name}_{Filename}, didn't notice the duplicating of information in the image name from the already named files!
4: realized my mistake and renamed but lost camera file name

any help appreciated,

ta.

no sorry, there is no way

It's somewhat scary that there's no undo for batch rename operations, given the damage a messed up operation can do.

At a technical level, it's not even difficult to allow undo (I implemented it in a different app) - just keep somewhere the list of files that were renamed and their new name, and use that to undo. It doesn't even need to be anything fancy - just the chance to undo the last batch operation only could save a lot of troubles.
