Batch rename

[TrailQuest]

When using the Name template, I'm looking for a list of variables that can be used inside the {braces}. Specifically, what I'm looking for is to save a 4-digit number in the original files name to the new file name. Each file has a different number, and they are not necessarily in sequence. E.g., img4637.heic to 20221004_4637XnView.heic. I've seen that variable called "Original File Number" but that does not work in XnView.

[xnview]

please try {Filename Number}

[TrailQuest]

please try {Filename Number}

Thank you for that. It works!

I'd still be interested in the list of variables that can be used in the {braces}.
